Microsoft is now offering a free tool that can lock down these public computers, its called the 'Shared Computer Toolkit' (SCT). This application allows you to lock down the computer's configuration, including Internet and application access. The SCT works by locking down the system through group policy settings, then replaces the boot partition every time the computer is rebooted.
