How to uninstall deep freeze manually using registry?

Answer 1

I've been using DF for a while and I never uninstalled it with registry. It seems to have a way to do this anyways here

You can also read more here about how to delete DF.

First and foremost, you cannot uninstall DeepFreeze until you thaw the machine. Otherwise the changes you made to perform the uninstall are lost along with everything else when you reboot.

Secondly, DeepFreeze works (in part) through a low-level kernel driver for your hard disk and sata/ide bus. There is also a service that runs, and you can disable that service (don't: it will break your system). But you can't just remove a kernel driver by changing a few registry keys. You need to also make sure you have an equivalent kernel driver to handle the disk requests (normally now, rather using the frozen method).

The normal way to uninstall DeepFreeze is to re-run the installation program. If you can't do this, you can still boot from a different location like a CD or DVD and re-install your operating system. Most frozen computers will also disable booting from anywhere but the frozen hard disk in the BIOS, and then lock the BIOS to prevent changes. This means you may also need to hard-reset your BIOS.

It's all software in the end, so I suppose there must be a way to do this on a thawed computer without re-installing the operating system - but it's more than just changing the registry. You've got to alter some files (probably using VolumeShadowCopy) that are used by Windows itself.

Answer 3

100% will work..

Try this: First have another unit to install deep freeze and do not put any password. Then, Boot thaw that unit. Copy the file at the root c:\ "Persi0.*" (something like this) Paste it to the root of the drive that you want to unfreeze, walla! that machine will be unfreezed. You can now uninstall DF after booting.
