Windows 10 downgrade to 7 not genuine problem

[kedo999]

So i reserved windows 10 a while ago and it was finally ready to update, so i did. After it was finished i spent about 10 minutes on it to discover that it really wasnt for me, so i downgraded through the system and security restore thing. Then when it was finished and i logged in, it said my copy of windows was not genuine and it keeps changing my desktop picture to just black and thats really annoying.

It seem that when you went back to Window 7 it can't pick up your OEM/SLP keys.

Could you fill in your My System Specs completely so we know what we are working with?
