This happened to me after I updated my Lenovo's drivers and had issues with driver power states. I was able to perform a restore by doing the following:
C:
cd C:\Program Files
attrib WindowsApps -h
this removed the hidden attributerename WindowsApps WindowsApps-renamed
exit
When the restore is complete, a previous version of WindowsApps
will have been restored.
To then go back and delete WindowsApps-renamed
:
cd C:\Program Files
takeown /f WindowsApps-renamed
rmdir WindowsApps-renamed /S
