"Could you also consider providing some access to unload Lite Step rather than having to uninstall it to get back to the desktop to use basic windows features."

From your popup menu (equivelent of start menu) go to litestep > utilities > Set Shell. Click the explorer button. It will ask if you would like to reboot. You don't have to reboot to have the shell change though. Just log out and back in again and you should see the explorer shell.
