Lockdown Vista PC.

Please could someone recommend a program for vista like SteadyState from MS.
I would like to restrict my limited accounts on my PC more and unfortunately
SteadyState isn't vista compatible. If there aren't programs available where
exactly should to configure desktop restriction in vista.

There is a program called Clean Slate that is made by a company called
Fortres Grand. We use it in several schools that we work for and only one of
the labs has Vista on it. It may not be the best software out there, but it
is a start.
