Vista Theme for windows Xp that won’t slow your PC down
I have been looking online and I did find a lot of themes for windows which made a transformation from Windows Xp to vista. But many were slowing down the pc. The best one would be vista Inspirat ultimate. It has nice features and has full options for disabling any feature if not needed and best of all, it takes very few resources and the PC won't even appear slowing down.
So, if you are trying out a windows vista theme for Xp, then try Vista Inspirat Ultimate. Google for it and you can download it.
