Mine is Windows Vista - The real thing
Plain old XP theme. I used to have a cool little green alien theme, 100% customised. I just sort of got sick of it. Surprisingly, it did seem to load faster than default XP, though, which has always confused me. My current wallpaper pic is of Kirby. I'll upload a screenie when I get home if anyone's interested :classic2:
The real pirated thing :evilb:
