Bootskin vista problems

For 2 weeks ago i installed lots of stardock stuffs so i could make my vista look more like Mac OS X, everything worked fine, after a while i wanted to get my start screen mac to, so i installed bootskin vista, worked fine to use the start screen mac, and after i got bored on mac, i uninstalled everything, everything works fine and everything now, but my startscreen doesnt dissapear as mac, its still mac, i uninstalled bootskin vista and impulse, didnt work either, i tried to install bootskin vista again and apply another skin like default screen, didnt work, please, how i get it to work? it looks so ugly.
