Deep Freeze Removal

Can anyone explain to me how Deep Freeze work? And how to uninstall it? I tried doing it using the software's setup pack, but it didn't work

Faronics Deep Freeze is a Ring 0 kernel driver and a very mature product. It's been attacked and hacked on for over 15 years now. Believe it or not it has been hacked several times by very smart people, usually programmers who know systems low-level type programming and driver development. And Faronics quickly patches any vulnerabilities. For legitimate *CUSTOMERS* who are genuinely stuck in a bad situation where they forgot their password Faronics can help you get your system back. But you must be able to boot from a Rescue USB or Windows Installation CD/USB. They will send you two NUL drivers to replace in c:\windows\system32\drivers which will allow you to boot your computer with Deep Freeze in Thawed mode. Then you can use the Deep Freeze installation file to uninstall Deep Freeze. Attempts to manually remove Deep Freeze are not recommended. Deep Freeze Standard/Workstation costs $48 as of March, 2021. From what I understand Deep Freeze is a Ring 0 filter driver, I think more than one.
