Windows XP Installing on another machine

So I'm reinstalling Windows XP on another computer, and I can't use the same product key because it's linked to the other computer that it was previously installed on, right?  So, is there a way to get an unlocked Product key?  I've looked around google a little and found nothing =\

You can use it, you just can't activate it, so you have to reinstall Windows every thirty days.
Just get a real OS already.

Hey faggot idiot. There are hundreds of cracks for XP to let you not activate it.
