I bought an win 7 pro key several year ago. I used it and upgraded it later on my old PC to win 10 and used it without any problem. Now I bought a new pc. I tried using me win 7 key to install win 10 but it won't work. When I upgraded it on the old one it didn't even asked for the key. Guess it just took the one from the already installed windows. But now with the new pc it didn't accept the key. What can I do now? Is there still a way to use my "old" win 7 key or do I have to buy win 10 now?
