Hi Jestoni,

We are currently investigating the issue and will update this thread when we have more information.

Advanced users can resolve the problem by trying one of the two options listed below:

Option 1:  Rename the WindowsApps folder in Safe Mode

1.    Boot into Safe Mode.
2.    Right click on Start and click on Command Prompt (admin).
3.    Type these commands below one by one.

             •    cd C:\Program Files
             •    takeown /f WindowsApps /r /d Y
             •    icacls WindowsApps /grant “%USERDOMAIN%\%USERNAME%”:(F) /t
             •    attrib WindowsApps -h
             •    rename WindowsApps WindowsApps.old
4.    Reboot back into Windows.
5.    Run System Restore.

Option 2:  Rename the WindowsApps folder from the Windows Recovery Environment (WinRE)

  1. Boot into WinRE.  To do this, click Start > Settings > Update & security > Recovery.  Then under Advanced startup, click Restart now.
  2. Click Troubleshoot > Advanced Options > Command Prompt.  Enter your administrator password when prompted.
  3. Type these commands, one by one:
    • cd C:\Program Files
    • attrib WindowsApps -h
    • rename WindowsApps WindowsAppsOld
  4. Reboot Windows.
  5. Run System Restore.

Regards.
