I just installed litestep but, i want my desktop to go back to the way it used to be.... how can i do this?

It is impossible.

You should have read all the warning's first.
There is lots of help in the sticky threads on this forum.

Welcome to Litestep ;]

P.S. To everyone else reading this, maybe this is how we can get new users? MUAHAHAHAHA!!!!

1) Set your shell back to explorer using the provided desktop shortcut.
2) Uninstall Litestep.
3) Be forever regretful of what you have missed.
