The worst part is that it's sort of like putting a fancier lock on your front door. If some one really wants to break into your house, you're not going to be safe just because you have a keypad, or a bump-proof lock. A crowbar or a broken window will do it.

It's pretty easy to get access to the files in a user account on Windows but just changing ownership. I guess they feel like a slight deterrent is enough.

Tom, I'm not aware of such a tool, but would be interested in finding one. I don't see these kinds of issues alot, but just in case...
