Update: The first testers will be able to access 50 select Android apps, according to Microsoft’s blog post. The new documentation says that the Windows Subsystem for Android “is currently only available through preview in the Windows Insiders Program.” However, as of right now, the Windows Subsystem for Android code isn’t in any external Insider test builds, including the Dev Channel. My guess is this will happen any day now, given the publication of the documentation. Update: And I was right. It’s today. In early September, Microsoft officials acknowledged that the promised Windows Subsystem for Android wouldn’t be ready in time for the Windows 11 launch on October 5, even though Microsoft had been touting the availability of Android apps on Windows 11 as a key new feature of the OS. There’s been a Windows Subsystem for the Android placeholder app in the Microsoft Store since early September. Update: Here’s more from Microsoft’s blog post about the first preview of the Windows Subsystem for Android. The subsystem is designed to make it so the curated list of Android apps and games can run side-by-side using the Snap Layouts feature, pinned to the Start menu or Taskbar and/or integrated into Alt+ Tab and Task view. Notifications from the Android apps notifications will show up in the Action Center and be able to be shared using a clipboard between a Windows app and an Android one. The Windows Subsystem for Android will be an app available from the Microsoft Store. The Android subsystem app runs in a Hyper-V virtual machine, just like the Windows Subsystem for Linux.
