How to Unfreeze Deep Freeze
1) Copy the Deep Freeze drivers (that will be used to unfreeze the system) to a USB drive. The folder should be at:
\\uno\staff\Shared\Docs\How To’s\Tech Procedures\Unfreeze Deepfreeze\Faronics_XNJ
Be sure to include the “locked” sub-folder.
2) Boot into a live cd; anything that has a windows environment and Command Prompt, even the windows install CD and the deployment CD. I used the deployment CD.
2) Get access to a command and prompt. If you’re using the scratch install disk, simply. Hit “shift+f10” after you’re booted into the setup. If you’re using the deployment disk, just start it up, hit “next” at the first screen, then “cancel” when it asks for your username and password; the “deployment” will fail and a command prompt will come up.
3) Plug the USB drive into the computer find where it’s been mapped. I ran the following command to get a list of mapped drives:
wmic logicaldisk get name
After this, I had a list of mounted drives. I just kept running “dir <letter>:” until I found the drive with the USB on it. You should probably do this to find out which drive letter the hard drive is on, too (refer to my poor example, “example.jpg”)
4) Copy the folder with your deep freeze drivers from your USB to the frozen computer. It’s easiest done with the following command (in this example, my USB drive is on “F”, the hard drive is on ” D”, and the folder with the deep freeze drivers is “Faronics_XNJ”):
xcopy F:\Faronics_XNJ D:\Windows\System32\Drivers /E
It will ask if you want to overwrite the drivers on the hard drive with your USB files. Type “y” for each or “a”.
5) Reboot the computer. It should now be unlocked.
6) To lock the computer again, you just need to move the files from “D:\Windows\System32\Drivers\locked” to “D:\Windows\System32\Drivers”, to overwrite the “unfrozen” drivers with the “frozen” ones. This can be done in your native windows system.
