So I just went out and bought a copy of windows 7 ultimate full, for a shitload of money, under the impression that I could use it more than one pc here at the house. Upon some research I have found out that it can only be activated on one pc at a time, with a total of 5 activations. Is this true? I feel like I just got raped by microsoft if that is the case. I would have just ordered the damn system builder version had I known that I would still be limited to use on one pc by buying the full version.
