LiteStep I am writing an article on it as we speak. LiteStep is a shell replacement it is not a theme or sound/screen saver theme it is a shell replacement just like in Linux. Your under a totally different environment. Still Windows but, not the same errors, not the same problems no restarts etc etc. Your replaceing explorer.exe to litestep.exe so explorer no longer is vaild and/or runs any more. Now let's say your having some major issues just restart the shell not your computer. Make sense? Also this is not Longhorn.
