I have several W7s laying around, and have installed it on several PCs. In the process of moving I have mixed up the PCs and the W7 DVDs, so I don't know which PC has which W7 on it. I don't normally peel the product key sticker and put in in the case because I swap stuff around too much.

Is there a way to determine which W7 is on which PC (all the same version so it's not like one is Ultimate and one is Professional and one is Home).

I just know one of you gurus will have the answer.

Thanks in advance.
