Just noticed up at RunAsRadio that my podcast I recorded with them about SteadyState is posted.
Richard and Greg talk to Todd Lamothe about Windows SteadyState. SteadyState allows administrators to configure PCs to roll back to a base configuration after every reboot. Combined with Group Policy for restricting access to resources you can create the perfect kiosk computer that cleans off all traces of the previous user, ready for the next.
Enjoy.
