omar, I'm trying to create a couple of regfiles that will make it somewhat easier to set/reset my shell. I've got the first one down no problem thanks to this thread, but is there a way to delete a registry entry (as in #3.) with a regfile. I'd like to have just two regfiles, one that sets the shell to LiteSTEP, and one that sets the shell to Explorer, but I don't know how to set up the regfile to get rid of that last entry.
