When installing Windows 8.1 without a Microsoft account, and also when integrating the PC in a Windows domain, very often the apps on the app screen show up with a “X” in the angle, or with “error” after their name.

It seems there is going something wrong in this configuration, as I saw this very often (my customers are all professional users, no home users).

I have found now a solution to this:

In short, the solution is the following:

– the owner of the key

HKEY_CURRENT_USER\Software\Classes\Local Settings\software\microsoft\windows\currentversion\appmodel\repository\packages

needs to be changed to SYSTEM (using the advanced button in RegEdit
– execute the following on an administrative command prompt

Powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml

to fix the Store app
– execute a Powershell with administrative rights and execute this command:

((Get-ChildItem “HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\InboxApplications”) | Get-ItemProperty).Path | Add-AppxPackage -Register -DisableDevelopmentMode

This was enough – no reboot needed, the store app loaded and also the single other apps.
