I have got windows 7 HP 64 Bit (I think its a trial, I haven't activated it yet) I got a key of this guy who works with computers and OS's and he gave me a key and I put it in but it said the only way I could activate it was over the phone and the phone said that it wouldn't activate because it might not be genuine but I check and it said it was genuine. What do I do?
Aslong as the actual key is genuine then there's no reason why Microsoft will decline.
Are you sure it's a genuine key? Try speaking to somebody in person on the helpline. (You mentioned you spoke with some sort of automated system)
