Windows XP ultimate...hmmm...did a quick search on Google and guess what comes up...a bunch of Torrent/warez sites
That's far from being legit. If it's what I think it is then it's just a copy of XP pre-loaded with a bunch of software and made into an ISO. Hardly anything legal or something you can buy at the store or anywhere. So now you're trying to convince me that somethin called XP Ultimate, which is a warez/hacked version of Windows XP which I don't know where it's been, is what's in and that everyone should have it and is better than any other Windows OS out there?
Get real bro...
