Reset the Windows Store app
If clearing just the Windows Store cache was not an effective fix in your case, you should also consider the fact that an installation inconsistency might be preventing you from using the Windows Subsystem for Android functionality. Note: Keep in mind that the Windows Store version on Windows 11 is still in preview mode, so inconsistencies related to its installation (particularly after an upgrade) are to be expected.

Delete the WindowsSubsystemForAndroid Local Cache folder
If you already tried resetting the entire Windows Store app and you’re still dealing with the same type of error (0x800700B7), the next thing you should focus on is the local cache folder that’s reserved for the Windows Subsystem for Android. Note: Keep in mind that this local folder is stored separately and won’t be deleted when you try resetting the Windows Store component or clearing the generic cache folder (methods above).

Perform an In-Place Repair

In this case, the first thing you should try is performing a repair install. Note: This operation will only touch the system files of your operating system. You get to keep your personal files, applications, games, media, and every other file present on the same partition as your operating system.

Perform a Clean Install
In case you already tried repair installing and the end result was the same 0x800700B7 when you attempt to run the Windows Subsystem for Android, the last result solution is to do a clean install to ensure that no system file corruption is actually causing this problem. But keep in mind that by doing a clean install on Windows 11 you will essentially do a complete wipe on the partition where Windows 11 is currently installed. Note: If you have any important data currently stored on the same partition as where your OS is installed, take the time to back up the data in advance before you start the clean install process.
