Windows App Studio being sunset

We want to directly thank each of the users of Windows App Studio and we want to be sure you have a smooth transition off when Windows App Studio service ends on December 1, 2017. What will happen to App Studio afterwards? Windows Template Studio is the evolution of Windows App Studio. We took our learnings from the code generation engine and the existing wizard to provide a strong foundation for our code generation and developer experience in Windows Template Studio. Best of all, it is open source over at

Details on the transition

Windows App Studio has been a free, online app creation tool that allowed enthusiasts and developers to quickly build complete Windows Universal Apps. Applications using Windows App Studio then could also be downloaded, extended and compiled with Visual Studio and submitted to the Windows Dev Center.

Any user of Windows App Studio will need to download your projects and data prior to December 1, 2017.

We’ll provide multiple email communications with users between now and December 1, 2017, but we want to be upfront and clear that you have a path forward to continue building great apps for Windows 10. We’re doing a phased approach with the sun setting process. Here are the three critical dates:

  • July 15, 2017
    • Only existing users can sign in
    • Finished application projects can be downloaded
    • No new dynamic collections data sources allowed to be created
    • Dynamic data will be allowed to be downloaded with a migration path provided
  • September 15, 2017
    • Application editor will stop working
    • Dynamic collections API will stop providing data to your existing applications
  • December 1, 2017
    • Windows App Studio will be shut down

Once again, we want to thank each of the users of Windows App Studio, and we view the smooth transition for users critical.

Ensuring Windows 10 devices are up to date has never been more important

The most secure Windows device today is an updated one: running both the most recent feature update – the Windows 10 Creators Update – and the most recent monthly quality update.

In each Windows feature update we build the latest security technology deep into the operating system, providing defense-in-depth features that prevent entire classes of malware from impacting your device.  In each monthly quality update, we add another layer of security, one that tracks emerging and changing trends in malware to make up-to-date systems safer in the face of changing and evolving threats.

Taking extra steps to keep systems updated and secure

Given the Windows 10 Creators Update provides the latest security protections to help keep you safe, we want to help update your device as soon as possible. In April, I shared as part of our commitment to your privacy, you will have the opportunity to review your privacy settings before your device is eligible to take the Creators Update. If you have not already taken this update, starting this week, we will prompt you to review your privacy settings.

You can choose to postpone this process up to five times with the next prompt asking for confirmation of your privacy settings.  It will only take a few moments for what we believe provides you with the best balance between privacy, security, and control.

Don't wait - review your privacy settings to get ready for the next update

Please note that we are not changing the update experience itself.  Once your machine is ready to update to the Creators Update, you still have choice over when that update happens as I described earlier in my April blog.

By staying up to date on both the latest feature and quality updates, you’re assured of being on the most secure version of Windows 10.  If you want to double check that your system is up to date, simply visit the Windows Security page and scroll down to click “Verify you’re updated.” We’ll let you know if you need to update your device to the Creators Update.  And, if you are having trouble updating your device, see this helpful article.

End of Service

As a reminder, the first version of Windows 10 is at end-of-service. While you can continue to use this version and your computer will still work, you will no longer receive the monthly quality updates that contain protection from the latest security threats. To remain secure your device should be updated to the latest feature update.  We will start sending a notification if your device needs to be updated to the latest feature update. If you have trouble, try these helpful tips.

Your privacy and security are important to us. We will continue to evolve our approach in providing a great Windows experience. As always, we encourage you to share your feedback as we grow and improve.  The Feedback Hub application is a great way to do this.
