I'm excited to finally share the first public preview of ShadowFreeze, a new lightweight disk virtualization tool for Windows.

ShadowFreeze allows you to freeze partitions, redirect all changes into a temporary overlay, and return the system to its original state with a simple reboot. The project aims to provide a modern, actively maintained alternative to classic disk-freezing solutions, while adding new capabilities and long-term support.

This is still a very early preview intended for enthusiasts and experienced testers. The core functionality is already usable, but many features are still under development and there has only been limited testing on different hardware and Windows versions.

Important Warning

The current preview build includes an unsigned kernel driver and installer. As a result, it can only be used on systems with Windows Test Signing enabled.

This build should not be installed on a production machine. Although it has worked well in my testing so far, it is still an early development build and may contain serious bugs that could lead to data loss or an unbootable system.

Please make sure you have a recent backup. Ideally, use a virtual machine or a dedicated test system.

I'm looking forward to your feedback, bug reports, and suggestions. Your testing will help shape ShadowFreeze into a reliable replacement for existing disk-freezing solutions.

Happy testing!
