I upgraded on 7/29 and none of my Store Apps work. Store app is grayed out with a download arrow. I have run sfc /scannow and DISM restore health commands. There are no issues. I saw a command to fix...

Can someone elaborate on Redgeneral's steps, specifically #6 as I get error messages such as:

Unexpected token '$(' in expression or statement OR
Unexpected token '\AppManifest.xml"

Please...
