My Windows XP Home CD requires activation or it's disabled in 29 days. My WinXP Pro CD doesnt require Activation at all.
Really, now I didn't know that (about the XP Pro that is). Send me a copy...heh heh heh, not really, but that is a good thing to know. My next computer is going to have Pro on it, and that means I can upgrade the XP Home on this one to Pro also.
My apologies to those of you who are purists, but if I buy and pay for it, I do not consider it wrong to use it where ever I wish (as long as it is on my own equipment).
