Announcing Windows 10 Insider Preview Build 17741 – Windows Experience Blog

Hello Windows Insiders!Today, we are releasing Windows 10 Insider Preview Build 17741 (RS5) to Windows Insiders in the Fast ring.

An easier way to get to Your Phone app
Android phone users, check it out and keep the feedback coming. Your Phone app is intended for Windows insiders, we brought it first to you because we need you to help us test and perfect this app! Build 17723+ is highly recommended for the best experience. Your Phone app is also live for Insiders who are in Skip Ahead running 19H1 builds.
Coming today for Build 17741, we’ve added a new entry point to Your Phone app. Notice a desktop pin? It’ll take you directly to Your Phone app – for quicker access to your phone’s content. Or go through the all apps list in Start Menu, or Windows key and search for Your Phone app. You pick how you get there, just get there.
Link your mobile phone to your PC through Your Phone app. Open Your Phone app and follow the setup flow. You will receive an app from Microsoft which you must download to your mobile phone and follow the setup prompts. Android 7.0 and above are compatible with Your Phone app. For PCs tied to the China region, Your Phone app services will be enabled in the future.

We’ve updated the Emoji Panel to now support search and tooltips for the Emoji 11 emoji that were added recently. These keywords will also populate text predictions when typing with the touch keyboard.
We fixed an issue where the taskbar flyouts (network, volume, etc) no longer had an acrylic background in recent builds.
We fixed an issue affecting certain apps where after quitting the app from its systray icon, the next time the app launched it would only display its systray icon (and not the corresponding open app window).
We fixed an issue in recent builds resulting in Spotlight taking an unusually long time to switch pictures after selecting “Not a fan” from under “Like what you see?”
We’re updating the image size limit for clipboard history (WIN + V) from 1MB to 4MB to accommodate the potential size of full screen screenshots taken on a high-DPI devices.
We fixed an issue where if you opened Cortana and then clicked the Notebook icon before starting your search, then window would end up truncated.
We fixed an issue where if Action Center was already open, Narrator wouldn’t announce incoming notifications.
We fixed an issue resulting in autoplay notifications not appearing recently until you pressed WIN.
We fixed an issue where if you received a toast, manually dismissed it, and immediately received another toast, you would hear the second toast ding but not appear.
We fixed an issue where if Settings was open to “Bluetooth & Other Devices” and then minimized to the taskbar, when you tried to resume the app Settings would crash.
We fixed an issue from recent builds where the first time you manually selected the date in Date & Time Settings, it would revert to Jan 1st.
We fixed an issue resulting in the Min/Max buttons in the Microsoft Store app frame overlapping the app content if it was open when switching from tablet mode into desktop mode.
We fixed an issue from recent builds resulting in share target windows (aka the app you select when prompted from the Share UI) not closing when you pressed Alt+F4 or the X.
We fixed an issue resulting in IMEs not being able to type East Asian characters into forms in Microsoft Edge.
We’ve made some adjustments to improve the amount of CPU that cdpusersvc uses.
[ADDED] We fixed the issue causing PCs to bugcheck (GSOD) when deleting a local folder that is synced to OneDrive.

Your PC will bugcheck (GSOD) when deleting a local folder that is synced to OneDrive. FIXED!
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.
After setting up a Windows Mixed Reality headset for the first time on this build with motion controllers, the controllers may need to be re-paired a second time before appearing in the headset.

Announcing Windows 10 Insider Preview Build 18219 – Windows Experience Blog

Hello Windows Insiders!Today, we are releasing Windows 10 Insider Preview Build 18219 (19H1) to Windows Insiders who have opted in to Skip Ahead.

Narrator Improvements
We have made the following changes and improvements:
Reliability: We have made improvements in Narrator reliability.
Scan Mode: Reading and navigating while in Scan Mode has been improved. Selecting text in Scan Mode has also been improved. Selecting forward in Edge has some known issues that we are actively investigating.
QuickStart: The link in settings to relaunch the QuickStart should now reliably be working and will launch from the very first Welcome page. The QuickStart should also more reliably take focus when Narrator is launched, which means Narrator should start reading it automatically.
Providing Feedback: The keystroke to provide feedback has changed. The new keystroke is Narrator + Alt + F. This will work both in the Standard and Legacy layouts.
Note: The Legacy layout also allows you to use Narrator + E to send us feedback.
Move Next, Move Previous, and Change View: When changing Narrator’s view to either characters, words, lines or paragraphs the Read Current Item command will read the text of that specific view type more reliably.
Keyboard command changes: The keystroke to Move to beginning of text has changed to Narrator + B (was Narrator + Control + B), Move to end of text has changed to Narrator + E (was Narrator + Control + E).
Braille: Improved usage of Braille commanding when using the Narrator key from the braille display.
For more information about Narrator new keyboard layout and other known issues, please refer to Intro to New Narrator Keyboard Layout doc (aka.ms/RS5NarratorKeyboard).

We fixed an issue resulting in Notepad’s “Search with Bing” feature searching for “10 10” instead of “10 + 10” if that was the search query. We also fixed an issue where accented characters would end up as question marks in the resulting search.
We fixed an issue where Ctrl + 0 to reset the zoom level in Notepad wouldn’t work if the 0 was typed from a keypad.
We fixed an issue resulting minimized apps having squished thumbnails in Task View.
We fixed an issue resulting in the tops of apps in tablet mode being clipped (i.e. missing pixels).
We fixed an issue where the taskbar would stay on top of full-screened apps if you had previously hovered over any grouped taskbar icon to bring up the extended list of previews, but then clicked elsewhere to dismiss it.
We fixed an issue where the icons in the Microsoft Edge extension pane were drawing unexpectedly close to the toggles.
We fixed an issue where Find on Page in Microsoft Edge would stop working for open PDFs once the PDF had been refreshed.
We fixed an issue where Ctrl-based keyboard shortcuts (like Ctrl + C, Ctrl + A) didn’t work in editable fields for PDFs opened in Microsoft Edge.
We fixed the issue where if the Narrator key is set to just Insert, sending a Narrator command from a braille display should now function as designed regardless if the Caps Lock key is a part of the Narrator key mapping.
We fixed the issue in Narrator’s automatic dialog reading where the title of the dialog is being spoken more than once.
We fixed the issue where Narrator won’t read combo boxes until Alt + down arrow is pressed.

If you encounter hangs running WSL in 18219, a system reboot will correct the issue. If you’re an active user of WSL you may want to pause flighting and skip this build. We’re working on a fix.
There are some improvements in this build but the dark theme File Explorer payload mentioned here is not there yet. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
You may see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store.
When using Narrator Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
When using Narrator Scan mode Shift + Selection commands in Edge, the text does not get selected properly.
We’re investigating a potential increase in Start reliability and performance issues in this build.

If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Announcing Windows Admin Center Preview 1808 – Windows Experience Blog

Hello Windows Insiders!Thank you for your continued interest in the Windows Admin Center insider preview! If you are new to the preview, check out the previous posts for the 1806 and 1807 releases.

Much of the work in this release was under the hood – we are implementing new infrastructure to support future scenarios and improving the experience for the Azure Site Recovery and Azure Update Management hybrid scenarios.
Server settings such as environment variables, remote desktop and RBAC settings are now available as a standalone tool at the bottom of the tool list in the Server Manager solution. Hyper-V host settings are also available on standalone servers and clusters with Hyper-V enabled. The Hyper-V host settings on a cluster allows you to change configurations across all cluster nodes at once!
In Virtual Machines, a new security settings section has been added to the individual VM settings.

We’ve also made updates to the Windows Admin Center SDK (Preview), as we prepare for our upcoming SDK GA.  We’ve added a CLI to enable easy creation of tools and solutions; added the ability to target different SDK versions; refreshed SDK examples for tool, solution, and gateway plugin; and updated our publishing options.

Preview: Apps & Features tool
Apps & Features is a new extension that allows Administrators to remotely manage the components that are installed on their Windows deployments.  When connecting to a Windows 10 client, the extension will load both the Apps (Store and Win32) that are installed, as well as the Features that can be enabled or disabled.  When you connect to a server, you will just see the Apps portion of the extension.  This feature is currently available in preview on our extension feed and can be installed from the Available Extensions in the Extension Manager.

Task Scheduler
Added weekly & monthly triggers, support for multiple triggers.
File share improvements
File sharing has been expanded to multiple tools and includes more features!  In the Files tool, now you can quickly share a folder, edit share permissions, or stop sharing a folder from the action buttons.  We’ve added the ability to set Deny as a permission option on a user or group, and the folder icon now indicates if a folder is shared.  Additionally, in the Storage tool on the file shares tab, you can now create a new share, edit a share, or remove a share.
Azure Update Management support in service mode (gateway installation on a server)
Last month when we released Azure Update Management support, the feature was only usable from Windows Admin Center installed on a desktop. The feature now works regardless of how you’ve deployed Windows Admin Center. Azure Update Management is a free service from Azure security and management that lets you manage and update all the servers in your environment from a central place.
Hyper-Converged Infrastructure
For Hyper-Converged clusters, the Drives > Summary page now shows the recommended reserve capacity to help you size volumes optimally. There are also two new charts on this page, showing the hit rate of the Storage Spaces Direct read cache (higher is better), and how full the write cache is (lower is better). To make advanced concepts like these more approachable, we’re added explanatory tooltips, with links to documentation, all throughout the HCI experience.
This month we also began work to make the Hyper-Converged Cluster experience responsive to different viewport sizes. The Drives > Summary page is a good example: whether your monitor is 1920×1080, 1366×768, or even if you have the browser window snapped to half the screen (e.g. 960px width), everything reflows elegantly and displays correctly. Note that we have NOT completed this work for certain pages, such as the Dashboard, just yet – stay tuned for future updates.

Windows Admin Center CLI
We’ve released the Windows Admin Center CLI as part of the SDK!  The CLI installs seamlessly alongside your other global dependencies by running ‘npm install -g windows-admin-center-cli’.  Once installed, you can create a new empty tool or solution with a single command, with more features planned in upcoming releases.  Read more about using the CLI in our SDK documentation.
Target an SDK version
Keeping your extension up to date with SDK changes and platform changes is easy.  We’re using NPM to tag the GA release, preview release, and latest versions of our platform dependencies.  Learn how to use those to update your development environment automatically, and switch between versions to validate your extension’s integration with our latest features.
Refreshed SDK examples
We’ve refreshed the tool, solution, and gateway plugin examples to leverage all the latest features in the Windows Admin Center platform, and the examples are now built on top of the Windows Admin Center CLI.  Check them out!
Publishing extensions and plugins
You have more options for publishing extensions and gateway plugins.  Now you can bundle a gateway plugin with an extension package.
What’s next?
We’re on the path to GA release of the Windows Admin Center SDK!  A number of additional improvements and new content are planned between now and then, stay tuned for updates.

Events – A expanding the navigation tree a couple levels deep, it may appear that there are many duplicate items. These are not duplicated, but the result of the content below that point being flattened in to one level. [18588187]
Microsoft Edge Browser – if you have Windows Admin Center installed as a service and using Microsoft Edge as your browser, connecting your gateway to Azure will fail after spawning a new (blank) browser tab. [17990376]
Tag filtering – if you select connections using the multiselect checkboxes, then filter your connection list by tags, the original selection persists so any action you select will apply to all the previously selected machines. [18099259]
HCI – The total size of the write cache is incorrect and variable, and the “donut” visualization can sometimes be out of sync with the legend values by 1 update cycle (30 seconds).

Registered Insiders may download Windows Admin Center Preview 1808 directly from the Windows Server Insider Preview download page, under the Additional Downloads dropdown. If you have not yet registered as an Insider, see Getting Started with Windows Server on the Windows Insiders for Business portal.

The most important part of a frequent release cycle is to hear what’s working and what needs to be improved, so your feedback is extremely valued. Send us feedback via UserVoice. We also encourage you to visit the Windows Admin Center space on the Microsoft Tech Communities forum to collaborate, share and learn from experts.

Announcing Windows Server 2019 Insider Preview Build 17733 – Windows Experience Blog

Hello Windows Insiders!Today we are pleased to release a new build of the Windows Server vNext Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience and Server Core, as well as a new build of the next Windows Server Semi-Annual Channel release, Microsoft Hyper-V Server and Windows Admin Center 1808.
In each preview release, there are two major areas that we would like you to try out:
In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016 or a previous preview build). Build-to-Build upgrade is also supported.
Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to.

To see the full list of new functionality introduced in earlier builds of Windows Server, plus updated installation instructions for the Server Core App Compatibility FoD Preview that includes support for Internet Explorer 11, see aka.ms/ServerInsider-WhatsNew.

A Faster, Safer Internet with HTTP/2 and CUBIC
The Internet is part of our daily lives at work and at home, and in the enterprise and in the cloud.  We are committed to making your Internet experience faster and safer, and in #8 A Faster, Safer Internet, a new post on the Networking Blog, we discuss how the features in Windows Server 2019 and Windows 10 bring those goals to reality. These goals are accomplished by:
Microsoft Edge on Windows 10 clients taking advantage of connection coalescing for HTTP/2, as supported by Windows Server 2019.
Improved security in Microsoft Edge browsers due to guaranteeing HTTP/2 preferred cipher suites.
Improved performance on Windows 10 due to Cubic, the new default TCP congestion provider.
For more details about these improvements, please see our blog entry: Top 10 Networking Features in Windows Server 2019: #8 A Faster, Safer Internet.
SDN Goes Mainstream
If you’ve ever deployed Software Defined Networking (SDN), you know it provides great power but is historically difficult to deploy. Now, with Windows Server 2019, it’s easy to deploy and manage through a new deployment UI and Windows Admin Center extension that will enable anyone to harness the power of SDN.
For more details about these improvements, please see our blog entry: Top 10 Networking Features in Windows Server 2019: #7 SDN Goes Mainstream
Cluster Sets (Hyperscale for Hyper-Converged)
We have announced cluster sets previously, but since then, we have done additional work to improve placement of virtual machines. While preserving existing experience of Failover Cluster management experiences on member clusters, an instance of a cluster set additionally offers key use cases around lifecycle management of a cluster set at the aggregate.
To recap, cluster sets is the new cloud scale-out technology in this preview release that increases, by orders of magnitude, the count of cluster nodes in a single Software-Defined Data Center (SDDC) cloud. A cluster set is a loosely-coupled grouping of multiple failover clusters: compute, storage, or hyper-converged. Cluster Sets technology enables fluidity of virtual machines across member clusters within a cluster set and a unified storage namespace across the set.
Please test out this new functionality and let us know what you think. You can find a short introductory video and links to more information on Microsoft Server & Tools Blogs: Cluster Sets in Windows Server 2019 – Hyperscale for Hyperconverged !!
Docs: https://aka.ms/Cluster_Sets on Windows IT Pro Center
Video: Learn all about Windows Server 2019 Cluster Sets on YouTube
Code: Microsoft / WSLab / Scenarios / S2D and Cluster Sets on GitHub
Feedback: csrequests@microsoft.com
Failover Cluster: Cluster Network Object
The Cluster Network Object (CNO) in a failover cluster is crucial to the management of a cluster. When creating a cluster, the creation process will detect the IP address scheme that is used on the network cards. If your network uses DHCP, the Cluster IP address will automatically get an IP address from your DHCP server. If your network uses static IP addresses, you will be prompted to enter an IP address to be used. However, there are only so many IP addresses that may be available, so we have introduced new functionality that is available when creating a cluster and the CNO.
You may be familiar with how a Scale-Out File Server (SOFS) works—an SOFS has a separate network name, and it is a distributed name. That means that the network name will take on the IP address of all the nodes. So, in DNS you can see the SOFS network name with an entry that is the IP address of the physical (or virtual) nodes. The system now offers that as an option for the CNO and will do some detection to make things a little easier, depending on how and where you create the cluster.
There is now a new switch for FailoverClusters, PowerShell cmdlets for failover clusters, called –ManagementPointNetworkType that you can use with New-Cluster. The options for this switch are:
Singleton: Use the traditional method of DHCP or static IP address.
Distributed: Use a Distributed Network Name using node IP addresses.
Automatic: Use detection. If running in Azure, use Distributed; if running on-premises, use Singleton (the default).
So, for example, to create a cluster utilizing Node1 and Node2 on-premises, where DHCP provides IP addresses, and to have the CNO as a distributed name, the PowerShell command would be:
New-Cluster -Name Cluster -ManagementPointNetworkType Distributed -Node Node1,Node2
If you use Failover Cluster Manager to create the cluster, it will default to using Automatic for the network type.

This makes creating clusters in Azure a much easier process, because there is no need to create an additional Internal Load Balancer (ILB) for the Failover Cluster.

[Server #####] Title of my feedback
We also encourage you to visit the Windows Server Insiders space on the Microsoft Tech Communities forum to collaborate, share and learn from experts.

[NEW] The Virtual Hard Disk Miniport Driver (Vhdmp.sys) may experience a bug check, SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e).
[NEW] A Remote Desktop connection may fail when Windows Defender Application Guard launches. This issue may affect preview releases starting with build 17727.
When a Windows Defender Application Guard container crashes, the resulting type of dump may be unexpected.
On a preview build of the operating system, Narrator is not available by default after installation. On an affected system, the audio service is disabled by default.
A Multi-Resilient Volume (MRV) may fail to mount during node maintenance for a software-defined datacenter (SDDC) cluster, causing virtual machines to go offline.
On recent preview builds, database applications might not be able to initialize a database and fail with a stack overflow or insufficient privileges when the database is located on an SMB volume.
Shielded VMs running Linux do not boot. The loader (LSVMLoad) waits for a passphrase for the boot partition.
Creating or modifying environment variables by using setx fails on a system running in a Nano Container (that is, Nano Server as a container image). On an affected system, setx requires a specific path in the registry, HKCUEnvironment, to exist by default. You can work around this issue by changing where the variable is stored in the registry, or you can add the expected registry path before executing setx commands. To specify that the variable be set for system-wide use in HKLM rather than in HKCU, the default, add the /M switch to a setx command. To instead add the expected registry path, run reg add HKCUEnvironment before executing setx commands.

This is pre-release software – it is provided for use “as-is” and is not supported in production environments. Users are responsible for installing any updates made available from Windows Update.   All pre-release software made available to you via the Windows Server Insider program are governed by the Insider Terms of Use.

Your Phone app is now LIVE!
Android phone users, check it out and keep the feedback coming. Build 17723+ is highly recommended for the best experience. Your Phone app is also live for Insiders who are in Skip Ahead running 19H1 builds. With Your Phone app, you get instant access to your Android’s most recent photos on your PC. Drag and drop that photo from your phone onto your PC. Copy, edit, or ink on that photo, right from your PC. Android 7.0+ are compatible with Your Phone app. For PCs tied to the China region, Your Phone app services will be enabled in the future.
For iPhone users, Your Phone app helps you to link your phone to your PC. Surf the web on your phone, then send the webpage instantly to your computer to pick up where you left off to continue what you’re doing–read, watch, or browse with all the benefits of a bigger screen. With a linked phone, continuing on your PC is one share away.
A Faster Safer Internet with HTTP/2 and CUBIC
The Internet is part of our daily lives both at work and at home, in the enterprise and in the cloud.  We are committed to making your Internet experience faster and safer, and in this blog, we discuss how the features in Windows Server 2019 and Windows 10 brings those goals to reality.
Windows 10 Microsoft Edge clients will take advantage of connection coalescing for HTTP/2 as supported in Windows Server 2019
Improved security on Microsoft Edge browsers by guaranteeing HTTP/2 preferred cipher suites
Improved performance on Windows 10 thanks to Cubic, the new default TCP congestion provider
For a full writeup detailing this improvement, please see our announcement A Faster, Safer Internet.

We fixed the issue resulting in the Clock & Calendar flyout sometimes not appearing until you clicked Start or the Action Center. This same issue impacted both notifications and the taskbar jump lists appearing. Thank you to all the Windows Insiders who gave feedback on this issue.
We fixed an issue that could result in an unexpected sihost.exe error when entering Safe Mode.
We fixed an issue where Timeline’s scrollbar didn’t work with touch.
We fixed an issue where when naming a tile folder in Start it would commit as soon as you pressed space.
As some keen eye’d Insiders noticed, we’ve been working on our scaling logic and you should find apps resize better now after monitor DPI changes. As always, we appreciate feedback in this space, so let us know if you have any issues.
We fixed an issue where the enabled/disabled state of Fast Startup would be reset to default after upgrading. After upgrading off of this build your preferred state will persist.
We fixed an issue where the Windows Security icon in the taskbar systray would become a little bit blurrier every time there was a resolution change.
We fixed an issue where the USERNAME environment variable was returning SYSTEM when queried from an un-elevated Command Prompt in recent builds.
We’ve updated the messaging in Snipping Tool to more closely align with the commitment we made here. You’ll also notice in the message that we’re exploring renaming our updated snipping experience – bringing together the old and new. The app update with this change hasn’t flighted yet, but if you have any feedback on the subject we’re open to hearing it.

The dark theme File Explorer payload mentioned here is on its way to Skip Ahead, but not yet there. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
You may see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store. If that doesn’t work, you can try to install a version of Office not from the Store.
When the Narrator Quickstart launches, Scan Mode may not reliably be on by default. We recommend going through the Quickstart with Scan Mode on. To verify that Scan Mode is on, press Caps Lock + Space.
When using Narrator Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
If the Narrator key is set to just Insert and you attempt to send a Narrator command from a braille display then these commands will not function. As long as the Caps Lock key is a part of the Narrator key mapping then braille functionality will work as designed.
There is a known issue in Narrator’s automatic dialog reading where the title of the dialog is being spoken more than once.
When using Narrator Scan mode Shift + Selection commands in Edge, the text does not get selected properly.
Narrator sometimes does not read combo boxes until Alt + down arrow is pressed.
For more information about Narrator new keyboard layout and other known issues, please refer to Intro to New Narrator Keyboard Layout doc (ms/RS5NarratorKeyboard).
We’re investigating a potential increase in Start reliability and performance issues in this build.

If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Announcing Windows 10 Insider Preview Build 17735 – Windows Experience Blog

Hello Windows Insiders!
Today, we are releasing Windows 10 Insider Preview Build 17735 (RS5) to Windows Insiders in the Fast ring.

We fixed an issue resulting in Reveal not working in Build 17733, for example in Start or Settings.
We fixed an issue resulting in links that launched one app from another app not working in the last few flights for some Insiders.
We fixed an issue in Windows Mixed Reality where the voice command, “Flashlight on,” would fail to activate the flashlight feature.
We fixed an issue resulting in Notepad’s “Search with Bing” feature searching for “10 10” instead of “10 + 10” if that was the search query. We also fixed an issue where accented characters would end up as question marks in the resulting search.
We fixed an issue where Ctrl + 0 to reset the zoom level in Notepad wouldn’t work if the 0 was typed from a keypad.
We fixed an issue where nearby sharing would become blocked on the sender device after canceling share to three different devices.
Narrator Scan Mode has been improved to prevent multiple stops for a single control.
We fixed the issue where Narrator said “Not a Narrator command” when navigating Win32 menu bar items.
We removed the Windows alert sound when performing the Narrator Find command.
We fixed the issue where Narrator got stuck at a word boundary when making a selection using select current and previous character.

Your PC will bugcheck (GSOD) when deleting a local folder that is synced to OneDrive.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store.
When using Narrator Scan mode Shift + Selection commands in Microsoft Edge, the text does not get selected properly.
Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.
We’re investigating a potential increase in Start reliability and performance issues in this build.

Announcing Windows 10 Insider Preview Build 17733 – Windows Experience Blog

Hello Windows Insiders!Today, we are releasing Windows 10 Insider Preview Build 17733 (RS5) to Windows Insiders in the Fast ring.

Dark Theme in File Explorer
With Build 17666 we started our journey bringing dark theme to File Explorer. Today’s build marks the turning point where we’ve finished what we set out to do for this release. Thank you to all Insiders that have shared feedback during this time!

Thanks everyone for your feedback about the XAML shadows we added recently. We’re taking them offline for the moment while we work on addressing some of the things you shared with us. You will also notice that the acrylic has been removed from some popup controls. They will be back in a future flight.
We fixed an issue from recently flights where the touch keyboard might become invisible on the screen.
We fixed an issue in recent flights where components of a notification with a progress bar (like the one when using nearby sharing) might flash every time the progress bar updated.
We fixed an issue where on certain devices if you reset your device and chose to keep files, after logging back into Windows the Sound Settings page would be unresponsive.
We fixed the issue where the High Contrast dropdown flashed when the values were changed.

We fixed the issue where Narrator couldn’t access all the emoji in the Touch Keyboard’s emoji panel.
We fixed the issue where Narrator didn’t say “selected” after image was selected using the keyboard.
We fixed the issue where Touch Narrator’s focus remained on the word even after deselecting it.
We fixed the issue where the Narrator key got sticky when using the Mouse Mode command.
We fixed the issue where Narrator’s Command Restore Default dialog was not read by Narrator.
We fixed the issue where Narrator’s copy and paste feature would say “selection removed” but the selection remained.
We fixed the issue where Narrator automatic dialog read the Command key Assignment dialog twice.
We have improved the Narrator experience when moving by character and announcing phonetic pronunciations.
We fixed the issue where Narrator focus and keyboard focus got out of sync after navigating TreeView controls.
We fixed the issue where Narrator misread the Calculator app’s display on focus for values over 100.
We fixed the issue where when launching Narrator QuickStart using the link in Narrator Settings, the Narrator icon would appear in the taskbar.
We fixed the issue where Narrator couldn’t read the label of the Word document recovery dialog.
We fixed the issue so Narrator can now navigate the New Notepad Status Bar contents.
We fixed the issue where Narrator Scan mode navigation didn’t progress after tabbing onto a link.
We fixed the issue where Narrator navigated out of the Microsoft Edge browser window using Scan mode on some web pages.
We fixed the issue where Narrator crashed when Developer Mode was in use and the generated string to display was null.
We fixed the issue where Narrator continuous reading got stuck on a table element in some HTML emails.

Your PC will bugcheck (GSOD) when deleting a local folder that is synced to OneDrive.
Clicking a link to launch one app from another app may not work for some Insiders. We’re investigating.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store.
When using Narrator Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
When using Narrator Scan mode Shift + Selection commands in Microsoft Edge, the text does not get selected properly.
We’re investigating a potential increase in Start reliability and performance issues in this build.
After setting up a Windows Mixed Reality headset for the first time on this build with motion controllers, the controllers may need to be re-paired a second time before appearing in the headset.
When using a Windows Mixed Reality immersive app, saying “Flashlight on,” may fail to activate the flashlight feature even though the status appears as active on the Start menu.

If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Have you read our latest story? An old discarded PC is gold to this Windows Insider, who revives old computers and donates them to community members in need.

And every Windows feature has a story. One of our favorites is the development of Eye Control, which Microsoft has been working on with the help of Steve Gleason, an NFL football player who is now living with ALS.

Announcing Windows 10 Insider Preview Build 17730 – Windows Experience Blog

Hello Windows Insiders!Today, we are releasing Windows 10 Insider Preview Build 17730 (RS5) to Windows Insiders in the Fast ring.
REMINDER: Our second RS5 Bug Bash continues to run through to August 5th, 2018. Keep doing all the Quests!

Your Phone app is now LIVE!
Android phone users, you can finally stop emailing yourself photos. Drag and drop that photo from your phone onto your PC. Copy, edit, or ink on that photo, right from your PC. With Your Phone app, live today for Windows Insiders, you get instant access to your Android’s most recent photos on your PC. Try it out by opening Your Phone app. You will receive an app from Microsoft which you must download to your mobile phone and follow the setup prompts. Build 17723+ is highly recommended for the best experience. Android 7.0+ are compatible with Your Phone app. For PCs tied to the China region, Your Phone app services will be enabled in the future.
For iPhone users, Your Phone app helps you to link your phone to your PC. Surf the web on your phone, then send the webpage instantly to your computer to pick up where you left off to continue what you’re doing–read, watch, or browse with all the benefits of a bigger screen. With a linked phone, continuing on your PC is one share away.
A Faster Safer Internet with HTTP/2 and CUBIC:
The Internet is part of our daily lives both at work and at home, in the enterprise and in the cloud.  We are committed to making your Internet experience faster and safer, and in this blog, we discuss how the features in Windows Server 2019 and Windows 10 brings those goals to reality.
Windows 10 Microsoft Edge clients will take advantage of connection coalescing for HTTP/2 as supported in Windows Server 2019
Improved security on Microsoft Edge browsers by guaranteeing HTTP/2 preferred cipher suites
Improved performance on Windows 10 thanks to Cubic, the new default TCP congestion provider
For a full writeup detailing this improvement, please see our announcement A Faster, Safer Internet.
Aligning the Insider Feature Update experience with Retail
When you are asked to restart for new flights, you will now receive the same notifications and experience as what we plan to provide to our retail customers. Depending on your ring, you will be asked to schedule your restart for the first couple of days, then we will ask if we could automatically schedule restarts outside of your active hours. Your participation in this experience will help us understand rough edges to improve before we release to retail.

We have fixed the issue impacting WDAG, Remote Desktop and Hyper-V. Remote Desktop Client (mstsc.exe) users should no longer see an error dialog complaining about low virtual memory when a connection is being established. And users can use enhanced sessions in Virtual Machine Connection (vmconnect.exe) again.
Thank you everyone who has given us feedback on the “Block Suspicious Behaviors” feature that was recently added to Windows Security. For the time being we’re removing it from the build while we work on addressing some of the things you shared with us.
We fixed an issue resulting in the volume slider in certain apps performing poorly with touch in recent flights.
We fixed an issue resulting in certain apps, like the Twitter app, not rendering content when navigating after a while.
We fixed an issue where expanding the Driver Updates dropdown in View Update History in Settings didn’t list anything (even when there were items to list) in recent builds.

Clicking a link to launch one app from another app may not work for some Insiders. We’re investigating.
We’re progressing in our work on adding dark theme in File Explorer and the Common File Dialog, but we still have a few things left to do. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
You may still see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
On Windows 10 in S Mode, launching Office in the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store.

Announcing Windows 10 Insider Preview Build 17728 – Windows Experience Blog

Hello Windows Insiders!Today, we are releasing Windows 10 Insider Preview Build 17728 (RS5) to Windows Insiders in the Fast ring.
Our second RS5 Bug Bash officially kicked off last Friday and runs through to August 5th, 2018. You know the drill – do all the quests!  Insiders in the Slow ring can also participate! AND we’ll be doing a Mixer webcast on Wednesday August 1st (tomorrow!) at 10am PDT.

You love your phone. So does your PC.

Coming soon, we’re bringing the first set of features to Your Phone app for Windows Insiders with an Android device. Snap a pic on your Android, see it on your PC. You can finally stop emailing yourself photos. With Your Phone app, your Android’s most recent photos sync to your PC automatically. Need to add a photo to your presentation? Want to spruce up that selfie with some Windows Ink action? Just drag and drop.

And rolling out in the coming weeks, Android users might also start to notice a desktop pin taking you directly to Your Phone app – for quicker access to your phone’s content.
To light up this experience, open Your Phone app. You will receive an app from Microsoft which you must download to your mobile phone and follow the setup prompts. Android 7.0 and above are compatible with Your Phone app. For PCs tied to the China region, Your Phone app services will be enabled in the future.
For iPhone users, Your Phone app helps you to link your phone to your PC.

From Joe Belfiore’s blog post on Microsoft 365, check out what we’ve got in store for you in a future WIP release. We’re working hard to bring these experiences forward soon.
Narrator Improvements
We have made the following changes and improvements:
Reliability: We have made improvements in Narrator reliability.
Scan Mode: Reading and navigating while in Scan Mode has been improved. Selecting text in Scan Mode has also been improved. Selecting forward in Edge has some known issues that we are actively investigating.
QuickStart: The link in settings to relaunch the QuickStart should now reliably be working and will launch from the very first Welcome page. The QuickStart should also more reliably take focus when Narrator is launched, which means Narrator should start reading it automatically.
Providing Feedback: The keystroke to provide feedback has changed. The new keystroke is Narrator + Alt + F. This will work both in the Standard and Legacy layouts.
Note: The Legacy layout also allows you to use Narrator + E to send us feedback.
Move Next, Move Previous, and Change View: When changing Narrator’s view to either characters, words, lines or paragraphs the Read Current Item command will read the text of that specific view type more reliably.
Keyboard command changes: The keystroke to Move to beginning of text has changed to Narrator + B (was Narrator + Control + B), Move to end of text has changed to Narrator + E (was Narrator + Control + E).
Braille: Improved usage of Braille commanding when using the Narrator key from the braille display.
For more information about Narrator new keyboard layout and other known issues, please refer to Intro to New Narrator Keyboard Layout doc (aka.ms/RS5NarratorKeyboard).

We fixed the issue resulting in the Clock & Calendar flyout sometimes not appearing until you clicked Start or the Action Center. This same issue impacted both notifications and the taskbar jump lists appearing. Thank you to all the Windows Insiders who gave feedback on this issue.
We fixed an issue resulting minimized apps having squished thumbnails in Task View.
We fixed an issue where when open Task View would crash if you pressed Alt+F4 and Timeline was enabled.
We fixed an issue where Timeline’s scrollbar didn’t work with touch.
We fixed an issue where the top border of UWP apps would still be accent colored even if having an accent colored border was disabled in Settings.
We fixed an issue resulting in the tops of apps in tablet mode being clipped (i.e. missing pixels).
We fixed an issue where the taskbar would stay on top of full-screened apps if you had previously hovered over any grouped taskbar icon to bring up the extended list of previews, but then clicked elsewhere to dismiss it.
As some keen eye’d Insiders noticed, we’ve been working on our scaling logic and you should find apps resize better now after monitor DPI changes. As always, we appreciate feedback in this space, so let us know if you have any issues.
We fixed an issue where Find on Page in Microsoft Edge would stop working for open PDFs once the PDF had been refreshed.
We fixed an issue where Ctrl-based keyboard shortcuts (like Ctrl+C, Ctrl+A) didn’t work in editable fields for PDFs opened in Microsoft Edge.
We fixed an issue where the icons in the Microsoft Edge extension pane were drawing unexpectedly close to the toggles.
We fixed an issue where the enabled/disabled state of Fast Startup would be reset to default after upgrading. After upgrading off of this build your preferred state will persist.
We fixed an issue where the Windows Security icon in the taskbar notification area (systray) would become a little bit blurrier every time there was a resolution change.
We fixed an issue where the USERNAME environment variable was returning SYSTEM when queried from an un-elevated Command Prompt in recent builds.
We fixed the issue where if the Narrator key is set to just Insert, sending a Narrator command from a braille display should now function as designed regardless if the Caps Lock key is a part of the Narrator key mapping.
We fixed the issue in Narrator’s automatic dialog reading where the title of the dialog is being spoken more than once.
We fixed the issue where Narrator won’t read combo boxes until Alt + down arrow is pressed.

We’re progressing in our work on adding dark theme in File Explorer and the Common File Dialog – you’ll notice improvements in this build, although we still have a few things left to do. You may see some unexpectedly light colors in these surfaces when in dark mode and/or dark on dark text.
There is an issue impacting WDAG, Remote Desktop and Hyper-V. Remote Desktop Client (mstsc.exe) users will see a misleading error dialog complaining about low virtual memory when a connection is being established. As a workaround, they can ignore that error dialog by just leaving it there. If they dismiss the error dialog, the connection will be severed. And users won’t be able to use enhanced session in Virtual Machine Connection (vmconnect.exe). As a workaround, they can stick with the non-enhanced session.
When you upgrade to this build you’ll find that the taskbar flyouts (network, volume, etc) no longer have an acrylic background.
When you use the Ease of Access Make Text bigger setting, you might see text clipping issues, or find that text is not increasing in size everywhere.
When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
On Build 17723 (but not Build 18204), you may see the notification count icon overlapping with the extension icon in the Microsoft Edge toolbar when an extension has unread notifications.
On Windows 10 in S Mode, launching Office from the Store may fail to launch with an error about a .dll not being designed to run on Windows. The error message is that a .dll “is either not designed to run on Windows or it contains an error. Try installing the program again…” Some people have been able to work around this by uninstalling and reinstalling Office from the Store.
When using Narrator Scan mode you may experience multiple stops for a single control. An example of this is if you have an image that is also a link. This is something we are actively working on.
When using Narrator Scan mode Shift + Selection commands in Edge, the text does not get selected properly.
We’re investigating a potential increase in Start reliability and performance issues in this build.
After setting up a Windows Mixed Reality headset for the first time on this build with motion controllers, the controllers may need to be re-paired a second time before appearing in the headset.
When using a Windows Mixed Reality immersive app, saying “Flashlight on,” may fail to activate the flashlight feature even though the status appears as active on the Start menu.

If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail.

Announcing Windows Server 2019 Insider Preview Build 17723 – Windows Experience Blog

Hello Windows Insiders!Today we are pleased to release a new build of the Windows Server vNext Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience and Server Core in all 18 server languages, as well as a new build of the next Windows Server Semi-Annual Channel release in English. In addition, the first preview of Microsoft Hyper-V Server is included with this build.
In each preview release, there are two major areas that we would like you to try out:
In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016 or a previous preview build). Build-to-Build upgrade is also supported.
Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to.

Click here to see the full list of new functionality introduced in earlier builds of Windows Server.
System Insights
In this Insider build, you can add new predictive capabilities to System Insights, without requiring any OS updates. This functionality enables developers, including Microsoft and third parties, to create and deliver new capabilities mid-release to address the scenarios you care about. New developer documentation and resources are now available, which help you write your own custom capabilities.
Any new capability can integrate with and extend the existing System Insights infrastructure:
New capabilities can specify any performance counter or ETW event, which will be collected, persisted locally, and returned to the capability for analysis when the capability is invoked.
New capabilities can leverage the existing Windows Admin Center and PowerShell management planes. Not only will new capabilities be discoverable in System Insights, they also benefit from custom schedules and remediation actions.
Deploying Kubernetes on Windows Server
Kubernetes is a popular orchestration tool for containers (see What are Containers) that makes deployment and management intuitive, scalable, and effective. This includes built-in features such as:
Scheduling: Given a container image and a resource request, find a suitable machine on which to run the container.
Health monitoring: Watch for container failures and automatically reschedule them.
Networking: Provide a network for coordinating containers to communicate across machines.
Service Discovery: Enable containers to locate each other automatically even as they switch hosts or change IP addresses.
Scaling: Add or remove container instances to match demand, either manually or automatically.
And much more! For guidance that walks you through how to install Kubernetes onto your on-premise Windows datacenter, please see How To Guide: Kubernetes for Windows Flannel (Host-Gateway). For more information about container orchestrators in general, see Container orchestrators on docs.microsoft.com.
Congestion Control with LEDBAT
Keeping a network secure is a never-ending job for IT Pros, and doing so requires regularly updating systems to protect against the latest threat vectors.  This is one of the most common tasks that an IT Pro must perform.  Unfortunately, it can result in dissatisfaction for end-users as the network bandwidth used for the update can compete with interactive tasks that the end user requires to be productive.
With Windows Server 2019, we bring a latency optimized, network congestion control provider called LEDBAT which scavenges whatever network bandwidth is available on the network, and uses it
For a full write up detailing this improvement, please see our announcement LEDBAT – Latency Optimized Background Transport

[Server #####] Title of my feedback
We also encourage you to visit the Windows Server Insiders space on the Microsoft Tech Communities forum to collaborate, share and learn from experts.

[NEW] On Nano Server, copying a file from an SMB volume in a container to local storage fails.
[NEW] A specific distributed search and analytics engine may by denied access when querying C:Windowstemp as ContainerUser. To work around this issue, set the paths for temporary folders to another location. For example, by using setx:    setx /M TEMP “c:sample”   setx /M TEMP “c:sample”
[NEW] A Multi-Resilient Volume (MRV) may fail to mount during node maintenance for a software-defined datacenter (SDDC) cluster, causing virtual machines to go offline.
[NEW] Services.exe should not launch Upfc.exe when a system starts if the system is running inside of a container.
[NEW] On recent preview builds, database applications might not be able to initialize a database and fail with a stack overflow or insufficient privileges when the database is located on an SMB volume.
[NEW] Virtual machines stop unexpectedly with exit reason 3, and they migrate repeatedly every few minutes.
[NEW] Preview releases of the operating system, starting with build 17698, may fail to detect a specific family of RAID controllers.
[NEW] Shielded VMs running Linux do not boot. The loader (LSVMLoad) waits for a passphrase for the boot partition.
[NEW] Draining a node may fail with an error: “Cannot create a file when that file already exists. (0x800700b7).”
Creating or modifying environment variables by using setx fails on a system running in a Nano Container (that is, Nano Server as a container image). On an affected system, setx requires a specific path in the registry, HKCUEnvironment, to exist by default. You can work around this issue by changing where the variable is stored in the registry, or you can add the expected registry path before executing setx commands. To specify that the variable be set for system-wide use in HKLM rather than in HKCU, the default, add the /M switch to a setx command. To instead add the expected registry path, run reg add HKCUEnvironment before executing setx commands.
The Virtual Machine Management Service (VMMS) may experience an error, APPLICATION_FAULT_INVALID_POINTER_READ, in Cluster Manager.
