Microsoft has always had an insidious tendency to change things just so that they are different and not because the change improves them.
The tool like the powershell command is to read your OEM key from the EFI... if you don't have a pre-built PC from Lenovo and co you don't have such a key.
Is there a Powershell (or similar) command that can fix the "@"-named Metro apps, which in my case are Alarms and Calculator? I also have @ZuneVideo and @ZuneMusic that should be Video and Music.

you can use "Get-AppxPackage" command in a PowerShell window with admin rights, and it will show the complete list of modern apps that you have installed, then you can use "Remove-AppxPackage -package PackageFullName" command (replace "PackageFullName" with PackageFullName of the app that you want to remove), and restart PC when you finish.
