THC,
This is what I am thinking his script would do... assumtion only

autorun litestep.exe
kill explorer.exe
separate windows process in reg
apply his wallpaper
and then have an option to back out this info and return to xp
maybe he did more I dont know.

Would have been cool to check out if I had a thumb drive.
I think it would be cool just for security.
Think about it.
Pull your thumb drive out and your interface disappears.
No hotkeys, nadda
Oh and you would have to change the wallpaper when locked to mees with ppl...
