One key, both versions. This genuine Pro license activates either Windows 10 Pro or Windows 11 Pro – install whichever you prefer, or upgrade from 10 to 11 later using the same key.
Why is OEM cheaper?
OEM keys are permanently tied to the first PC they activate on. Same genuine Windows, same Pro features – the only difference is you cannot move it to a new machine. If you will stay on this hardware, OEM is the smarter buy.
What you get: a genuine activation key delivered instantly after purchase, plus simple activation instructions. Full Windows Pro features – BitLocker, Remote Desktop, Hyper-V and more.
