OEM Windows 11 Pro keys are tied to the laptop and can’t be moved. If you have a retail key, you can transfer it. Otherwise, you can get a new key from Noxkeys for about $13.
Yeah, Windows 11’s right-click menu hides too much. Since tools like ShellMenuView don’t fully work with it, try using WinAero Tweaker to bring back the classic context menu then you can manage and clean it up more easily. Makes “Delete” and other useful options show up right away.
