I've just picked up a pc which I had to re format the hd.The system originally had xp home installed,but I don't have the original install disc.THe case has the product key sticker on It. Is it possible to install xp home from a different disc and use the original product key, or is there a way to get a copy of the original disc? It would be nice if I could, as this pc should have a legit copy of xp home which has been bought and payed for. I think I already know the answer,as we all know microsoft!!,but any input would be apprecieated.
