Forgetting to save files to an external drive or a designated "ThawSpace" results in permanent deletion after a restart.
Deep Freeze V6.20 represents an older generation of Faronics' endpoint protection software . Its core functionality remains the same as modern versions: it creates a "Frozen" snapshot of the system. When the computer restarts, it resets to this snapshot, effectively wiping out any alterations made during the session. Key aspects of this version include: All changes are lost on reboot. Thawed State: Changes are saved permanently.
In version 6.20, if an attacker or administrator booted the machine into an alternative environment (such as a Linux Live USB or WinPE disk), the Persi0.sys driver would not load. From this external environment, the user could directly modify or delete the Deep Freeze configuration files ( Persi0.sys on the root of the C:\ drive), effectively breaking the freeze cycle upon the next native Windows boot.
To make any changes, you must open the hidden Deep Freeze user interface on the local machine: Fuck Deep Freeze V6.20
Forgotten administrator passwords are incredibly common. Years pass between needed accesses, and without documentation, recovery is nearly impossible. Users end up scouring forums for solutions, often resorting to unofficial tools just to regain control of their own computers.
Older versions of Deep Freeze relied heavily on the system BIOS/UEFI clock to validate specific timed configuration states or evaluation periods. Technicians discovered that altering the system time via the BIOS before Windows booted could occasionally cause the Deep Freeze driver to malfunction or enter an uninitialized state, leaving the drive temporarily thawed.

If you are managing a lab or have lost access to your own machine, use these official methods: Forgetting to save files to an external drive
If a computer crashed or a student forgot to save to a USB drive before a reboot, hours of work vanished into the ether.
If you are an administrator or a user with authorized access who needs to change settings, update software, or disable Deep Freeze v6.20, you do not need to resort to destructive measures. 1. Accessing the Control Console
A native feature built directly into Windows 10/11 Enterprise and IoT editions. UWF redirects all writes to a virtual overlay memory space, providing a built-in, robust "freeze" capability without third-party software. When the computer restarts, it resets to this
The redirection is turned off. Any changes made to the system during this time become permanent.
To make permanent changes to a computer protected by Deep Freeze, you must place it in a "Thawed" state. Below are the standard methods for interacting with the software: 1. Using the Graphical User Interface (GUI)
