When third-party tools fail due to Deep Freeze updates, the manual file-swapping method remains the most reliable, verified workaround. This process bypasses the Windows OS entirely so Deep Freeze drivers cannot load.
During boot, Deep Freeze checks for a specific keyboard hotkey (usually Ctrl+Alt+Shift+F6 or Ctrl+Shift+Alt+F1 ) to enter the configuration panel. By injecting a custom bootloader (like DFBoot.exe ) from a rescue disk, you can reset the password to admin or blank.
Deep Freeze stores its configuration data, registration details, and encrypted password hashes in a hidden system file named Persi0.sys , typically located in the root directory of the boot drive (e.g., C:\Persi0.sys ).
In your Enterprise Console, go to , enter that Token, and click Generate OTP .
Renaming Persi0.sys to Persi0.sys.bak breaks the Deep Freeze driver configuration. When the system reboots into Windows, the driver may default to an unconfigured state, allowing you to open the interface without a password or completely reinstall the software.
All data written to the drive is redirected to a temporary cache space (a thawspace or allocation table allocation). On reboot, this cache is cleared.
Enter this generated OTP into the locked workstation's login dialog. This will grant immediate access to the console, allowing you to change the status to "Thawed" or set a permanent new password.
Locate the core driver files within C:\Windows\System32\drivers\ named FrzState2k.sys and rename them as well.
