Re: is this vista?
looks like it, maybe its cheap because its a 64-bit, and pretty much the people that knows about computers use 64-bit, and this can only go on 1 computer, so if you put it on one computer, it can only be on that computer.
now i am not sure how the serial key knows, i think it has to do with the motherboard. so if you switch mobos, you will need to get another copy.
if i am wrong, please correct me
