Steady State ∞

Windows SteadyState [discontinued] does imaging which is disk-intensive.

• Group Policy Settings for Creating a Steady State
• Creating a Steady State by Using Microsoft Technologies

• Windows SteadyState Reference Spreadsheet

What one guy does:

• Symbolic link user folders and data to equivalents on the D Drive, and continue keeping their Documents on the NAS.
• SafeGuard / Guest Mode the user accounts and use Disk Protection on the C: Drive to revert the contents on reboot.

• Use AppLocker to eliminate the possibility of running anything un-sanctioned.
