I believe there are actually several options assuming the problem occurred
after a full reboot of the system:
* using the .gdb extension and having file system protection and/or volume
shadowing enabled (although my memories are vague on this, and I am not
sure this applies to current Windows versions)
* having the system in a kiosk mode where a reboot restores an image of
the last know 'good' config of the system (but this is something that
usually requires very explicit configuration)
