You should get infinite activations with the key, AS LONG AS, it is used on the one computer, when you use it the second time, I should think you have to phone microsoft to reactivate it, I take it they kept the situation the same as XP, so thats what i'm going by.
XP usually generates a key for the computer hardware to check its on the one computer and if not asks you to reactivate, where microsoft can see past activations etc. All in place to simply stop you installing on as many PCs as possible.
