Windows Seriel Number Question

If you have two computers on the same network and you try to install xp pro on one and you use the same seriel as you used on the other one on the network and it's not a legit copy will windows see it and mess up? Also I don't endorse pirate copies of windows. This is a hypothetical.

No, you're a fucktard for expecting a key that works with windows update.  Keep up with the times!  They have a validation thing now and the best choice is to use the windows update validation crack thats floating around.

Google, motherfucker.  you use it?
