The Android compatibility layer of Windows 11, commonly known as Windows Subsystem for Android (WSA), comes without the Google Play Store or any kind of Google apps. Instead, you get the Amazon Appstore as the built-in solution for downloading third-party apps. While it is possible to manually sideload apps on WSA, there is no simple way to manage all the installed apps on the Android subsystem — unless you install a launcher, or go one step further and enable the Play Store.
