Windows 7 64-bit Activation Error 0xC004c008 with Valid OEM Key
I had to replace my motherboard due to 2 bad caps and when ever I am in anything full screen that uses video I get a popup that says I must validate my Windows 7 which I thought was odd because I validated it years ago. Then I remembered hearing something about how now with Windows it has something in it where if any hardware changes you now have to re-validate Windows. I don't know why this is but I realized that is what was happening so I got my CD key out and typed it in.
But then I got this error which shocked me as I thought this would be easy:
0xC004C008
