Q: Win 10 System Restore Fail 0x80070091

Below about says it all.  I tried SysRes from two points, both with same failure.  

System Restore did not complete successfully. Your computer's system files and
settings were not changed.

System Restore failed while restoring the directory from the restore point.
Source: AppxStaging
Destination: %ProgramFiles%\WindowsApps
An unspecified error occurred during System Restore. (0x80070091)

The two attempts were from: choose a different restore point>show more restore points type Backup.  I really need this function to work.  Any solutions out there?

Thank you,




Renaming folder WindowsApps, reboot the system and try a system restore should cure the issue.

I've described a solution here Windows 10 Version 1607: System restore error 0x80070091 [Fix]

Addendum: It seems that the issue has been fixed in Windows 10 Creators Update. And there is a batch file to fix the issue. Further details may be found here:
