I'm having activate windows now problem.
I had to rebuild my computer due to bad motherboard and CPU issue. So I had to replace my motherboard and CPU. I kept the same hard drive, so I didn't have to re-load Windows.
Now i get a message Activate windows now. When I try to use my product key, it associates the key to my old motherboard I assume, so it will not accept my product key.
What do i need to do to get my product key to work?
