    Deep Freeze is a program that prevents changes to a hard drive. You can do whatever you want to the drive, but when you restart it will return the disk to its original state.
    It does this without partitioning, taking up extra space, or having another hard drive to image across.
    Anyone have any ideas or theories on how it works :confused:

    Of course it needs extra space!. It must store the changes somewhere, otherwise OS would NOT work
    It behaves just like any of virtual apps currently, it make OS & applications "believe" that they are actually writing to registry & the file system and on reboot it simply clears its cache, so everything is back to normal

    Yeah they use these kinda programs at Internet Cafes to delete all the crap that users do or download to a system. Very good solution for them. not for home use though IMO

    Very interesting (From disk-utilities.com/time-freeze/):

    ..........................................................................................................
    » Keep system safe from threats of viruses, spyware, worms, Trojans, etc.
    » Enter virtual system in 2 clicks, no need to reboot computer
    » Easy system restore and recovery to remove all problems
    » Surf internet safely, and test software & game installations without fear
    » Robust MBR protection guarantees the normal startup of PC
    » New protection mode greatly improves efficiency of virtual system
    ...........................................................................................................
    More flexible switch between virtual system and real system: To enter virtual system, you don't need to reboot computer; to return to the real system, just exit system protection mode, and you can discard virtual system data or save them to the real system freely.
    ...........................................................................................................
    WonderShare Time Freeze 2.0.0 seems to be what i was looking for. :D

    Deep Freeze 7 needs to reboot to change protected/unprotected mode.

    Could be in most cases...but IMO if you need to use REAL GPU it's the only option.
