Generic Windows 10 Key cannot be used Error code: 0xC004C003
So after a bad mess last night I had to re-install windows 8.1, then upgrade to windows 10. I tried using my Windows 8.1 key for installing Windows 10 but it denied it. I read about a program called Ultimate PID checker. That can find your key. So I found my supposed Windows 10 Key that is what everyone is calling generic. Now windows is telling me:
So what do I do? Do I have to restart ALL Over and skip the CD key input?
