Hey, I have a computer with windows 7 genuine that I am replacing soon and I dont want to buy another copy of windows 7 (i am buying a new hard drive) I still have the windows 7 disc, but wont I have to buy another activation key? I dont care much about backing up old file, all i have really is games. I just dont want to have to buy a new copy and I want the genuine edition. Is there a way around this? like isn't there a way to get your activation key from the current computer and use it on another computer?
