I didn't say it wasn't possible to use it.. I said it was against microsofts terms of agreement. like I said in an above post that I work for computer repair / build company that is partnered with microsoft. A representative comes out from microsoft and sits us down to tell us a few rules and goes over the terms of agreement with win xp. In the win xp home version you are not alowed to use the same cd key on 2 different systems relating to there barebones. Regardless if anyone wants to disagree because they dont want it to be true doesn't change the fact its illegal to use em on more than 1 machine. I wish it were the other way around also cause I wouldn't have to buy a key for everyone of my customers. Don't make up false statements cause you want to disagree with someone, and why would you call someone a wuzzie in these forums? everyone here is very intelligent and even when disagreeing keeps it an intelligent conversation and no one resorts to name calling or degrading someone else. So if you want to do that I would suggest maybe another forum, or eventually no ones going to take you seriously. I know I wont.
