"Okay, so I bought myself a used P4 system for cheap -- with WinXP Home still on the hard drive. I open up the case, everything checks out fine, then I upgrade the memory ... and suddenly Windows informs me that it needs to be reactivated because I've made too many changes to the hardware! (Thanks a lot, Micro$oft.) So I wipe the hard drive and install WinXP *Pro* Editio
