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

You can try System Restore again and select a different restore point. If you continue to see this error, you can try an advanced recovery method.

It usually doesn’t help to try a different restore point because the same error code is displayed again. The error message shows that there are problems with restoring the “WindowsApps” directory . Unfortunately, these directory problems are not so easy to solve, you have to choose the following solution.

Windows 10 startup in safe mode

First you have to start Windows 10 in safe mode , otherwise the Windows Apps directory is always accessible and you cannot make any changes to it. Please copy the folder ” C: Program Files WindowsApps ” away, including all files and subdirectories, so that you have a backup of it, there are other problems.

Then please open the MS-DOS prompt and enter the following commands one after the other.

CD C: Program
TAKEOWN / f WindowsApps / r / d Y
ICACLS WindowsApps / grant “% USERDOMAIN% % USERNAME%“ 🙁 F) / t
ATTRIB WindowsApps -h REN WindowsApps WindowsApps.xxx

If the renaming of the Windows Apps directory does not work, you can also delete the directory, because you made a backup of it beforehand. Either you delete the directory using Windows Explorer or using the following command, which recursively deletes the directory and all subfolders contained in it.

rd / s WindowsApps

If you’ve done all of this, you can now try Windows System Restore again . Now the error code  0x80070091 should no longer occur.
