I'm sure it's been suggested before but I'll reitterate it again. It would be ideal to have CCleaner able to clean multiple user directories (on 2k, XP etc)right after having been installed. I've heard of some ways to accomplish this by going in and adding things after the install, but unfortunately I don't have time to fiddle with that sort of thing. I'm currently using another tool to accomplish the same thing, but it's clunky and I figure Piriform guys should be able to come up with something smoother.
