I am SO stupid about this
Can I use the same XP installation disk that came with my PC or do I have to buy XP new?
Actually all that has to be done is remove the original installation and the OP is free to reinstall it on any hardware they own. It's a one machine at a time license, and since they own the original hardware it came with, they're in the clear legally, morally, and technically. As a former MS reseller and OEM, I can tell you this is the way it's always been.
BTW, OEM Windows is identical to Retail, it's not "tied" technically to hardware in any way, period. It's just licensing.

Um... no, that is incorrect. Perhaps you were a former reseller before Microsoft released XP/Vista activation/validation/"genuine Windows"? Activation ties the OEM license to the PC (characteristics of the motherboard), and if/when you try to reinstall on a new PC, it won't activate, it will say your copy of Windows is not genuine, and then kindly offer to sell you a new license over the Internet.As a former MS reseller and OEM, I can tell you this is the way it's always been.
