I had bought a retail copy of Windows 8 Pro for my laptop some time ago and when I built a desktop PC recently, I decided to use a retail copy of Windows 8.1 for it. Since then, the laptop has been updated to Windows 8.1 Pro.
Now, is it possible to use the Pro license on my desktop and the other on my laptop? Is it possible to swap them like that? I'd like to do it before upgrading to Windows 10.
