Is it Windows XP or Vista?
It is as the screenshot says Windows Vista.
But I think it looks kind of neat like this, I have found Aero to be a little bit jarring at times. But this is nice looking. Overall though I still am very much glad that I have Windows Vista on this box over XP which whilst fine, does have some annoyances when you use Vista a lot elsewhere e.g. desktop wide search built into start menu, and the nice improved Windows Explorer.
