What Is Deep Freeze?

For those unfamiliar, Deep Freeze is a kernel-level software solution that “freezes” a computer’s hard drive state. Upon reboot, the system reverts to a predefined configuration, undoing any changes made during the session—whether accidental misconfigurations, unwanted software installations, or malware infections. Version 8.63 sits in the mature branch of the software, widely used on Windows 7 through Windows 11 systems.

Frequently Asked Questions (FAQ)

Q: Is Deep Freeze 8.63 Patch free for existing license holders?

• A: Yes, if you have an active Maintenance and Support (SnS) agreement or purchased a license after June 2022. Without SnS, you may need to renew to download the patch.

Q: Does the 8.63 patch require uninstalling the old version first? Key Benefits of Installing the Deep Freeze 8

• A: No. The installer handles in-place upgrades. However, you must be in a Thawed state. Attempting to install while Frozen will result in the error: "Deep Freeze is currently Frozen. Please boot Thawed to continue."

Q: Will my existing ThawSpace and thawed folders survive the patch?

• A: Yes. ThawSpace partitions and the "Thawed Folders" list are preserved because the patch only updates the kernel and service, not the boot record or partition tables.

Q: My antivirus flags the 8.63 installer as suspicious.

• A: False positive. Deep Freeze’s kernel-level behavior mimics some rootkit techniques (intentionally). Add the installer and C:\Program Files\Faronics\ to your AV exceptions before patching.
