In this article, we will show you how to remove Deep Freeze password and uninstall it without using any third-party Deep Freeze password remover.
Part 1: How to Remove Deep Freeze Password
To remove the password of Deep Freeze, you can replace Persi0.sys file by downloading and installing another program with the same version number. This file is the password file of Deep Freeze and it is located in the C drive. Here are the steps to follow:
Launch Deep Freeze on the PC where you installed this encrypted program, and check the version number, then remember it.
Download another Deep Freeze software whose version number is similar to the encrypted one on another PC. Once downloaded, install it on your computer.
After installation, set a password that is easy for you to remember, like 1234. Then click on Apply and Reboot and your computer will start rebooting.
Boot the operating system with a WinPE USB drive or disk. Then open the Disk C after booting and locate the file Persi0.sys, which is the password file of Deep Freeze. Copy this file to your USB drive as a backup.
Like the previous step, boot the operating system on the computer you installed the password-forgotten Deep Freeze and open Disk C, find the file Persi0.sys and hit Delete. Then paste the Persi0.sys file stored in USB to Disk C to replace the previous one.
Once replaced, reboot your system. If you succeed restarting your PC, then you can check whether the date of Persi0.sys file is current. If it is current, that means you replace successfully.
Hold down the Shift key and hit the Deep Freeze icon, enter the password 1234, if you can open the setting windows, that means you successfully removed the password you forgot.
