Background
Windows Subsystem for Android was first confirmed at the "What's Next for Windows" event on 24 June 2021, right after the announcement for Windows 11. It was later publicly introduced on 20 October 2021, with the first preview version available to Windows Insiders in the Beta Channel on the same day.

It's currently available in the United States only.

Windows Subsystem for Android is partially based on Windows Bridge for Android, a deprecated Android runtime environment for Windows 10 Mobile known as "Project Astoria", and run as a virtual machine under Hyper-V. It also utilizes Intel Bridge Technology, a runtime post-compiler for running ARM apps on x86 based processors.
