One key, both versions. This genuine Windows Home license activates either Windows 10 Home or Windows 11 Home – install whichever you prefer, or start on Windows 10 and upgrade to Windows 11 later using the same key.
Retail vs OEM – which do you need?
Retail keys travel with you, not the machine – if you upgrade your PC later, deactivate on the old one and activate on the new one. OEM keys are permanently tied to the first machine they activate on; they are cheaper, but the license stays with that hardware.
What you get: a genuine Windows Home activation key delivered instantly after purchase, plus simple step-by-step activation instructions.
