Upgraded to 8.1 months ago with no problems.
Just in the last week or so, when trying to access the app store, it closes immediately after i try opening it. All my other apps open and work fine.
After looking at other threads I've tried the most common fix of pasting
"Powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml" into command prompt as admin and pressed enter
it then reads
"Deployment operation in progress: C:\Windows\Winstore\AppxManifest.xn1 Processing
[0000000000000
]"
I then try opening the store again and nothing has changed, it still closes straight away.
I've also checked that SYSTEM is chosen for the Owner, which it was, so nothing to change there.
At a loss at what else to try as all the threads and forums i've looked at have suggested these things and they've worked for most people?
Thanks.
