Windows Store then returned the dreaded error code 0x80004005 ;
I managed to solve it using the following steps- I'm no professional but this worked great and there's nothing fishy ☺:
- Press Windows Key to start the Run command ;
- Type "WReset";-without the quotes.
- -in this step it is important to have a working internet connection.
- Give the Store some time before it can display all the available apps.
- Close the Windows Store app when everything looks normal .
- Run the "powershell.exe"; - without the quotes.
- From that you should see the "Majestic" Powershell window.
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
Once your powershell looks like that: Just press Enter key.
You'll see it executing some stuff. That's good- unless there is an error.
FINALLY. Save everything and Close everything and Restart your Windows PC.
This process worked for me and sometimes it's just a matter of luck.
