Windows 10: Windows 7 key not working on 10

I got an old computer from my parents that had some corrupted files on the hard drive so i formatted the drive and reinstalled Windows on it. It was Windows 7 when they had it and i installed Windows 10 on the computer. When i go to activate the Windows 7 product key it says it is not valid. I am not sure why the product key is not working and yes i checked the key 4 times and all the letters and numbers are correct. I am installing updates on it now and will try again when that is done. Is there a reason why that product key will not work? Only thing i can think of is that it is a Windows 7 key but i thought all keys from 7 to 8 would work for 10.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

I just did a deployment last night with a fresh 10 install using the newest ISO and a 7 Pro key, worked like a charm. Glad yours worked for you as well. *Toast :toast:
