As far as I know that there are several skin packs available for several OS which will transform your computerís desktop. They very easy to install and customize the desktop. I donít know whether they are safe to use or not. There are already Windows desktop enhancements similar to themes, launchers, skin packs and Transformation packs for Windows 7. In that one is my best Alienware theme pack. The Red one is extremely beautiful and feels like you are in powerful gaming environment.
