Windows 8.1 – Store won’t open after upgrade

/ Articles / 2021-09-07

After upgrading Windows 8 Enterprise to Windows 8.1 Enterprise (RTM), the store app won’t launch anymore, hanging on the splash screen forever. Is there a trick to reset the store app or something? Restarting or killing the app didn’t work. There are no error messages in the event logs (TWinUI/Operational etc.).

Solution:

Found this on another forum. Open a command prompt and run the following:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage           -DisableDevelopmentMode            -Register $Env:SystemRootWinStoreAppxManifest.xml
