Can you transfer Windows 10 Pro license to another computer?
From an OEM Windows 7, Windows 8, or 8.1 licenses upgrade, these are licenses that come preinstalled on a new computer from a manufacturer, and then your Windows 10 license maintains the OEM rights – cannot be transferred. If you have a full retail copy of Windows 10, you can transfer it as many times as you want.
