[Solved] Windows Vista Ultimate Black v2

Hi, my hard drive toasted a few weeks ago, and when I send it to a programmer to install a new one, he also installed Windows Vista Black v2(which I have never heard of) without telling me. I was going to install XP pro again.
So my reason of starting this thread is because I want to know if vista black is good. So far its given me a few big headaches as I can't even play minesweeper and hear windows media player at the same time(annoying system crash). But I like all the fancy apps(office word,winrar,100+ sidebar apps,etc.).
Another problem is, Is it real or some piraty thing? I ask this because the vista button is blue and diamond shaped and ugly, unlike other vista buttons.
Should I change it back to xp pro, or ubuntu 9.04 when it arrives from mail, or keep it?
Thanks.

no, the guy has the key, back up cd, and its been asking me for a key to tune up utilities, which is another reason I think this is a crappy piraty clone.
