Shadow Defender 1.5.x

A high-performance system-freezing utility that runs your OS in 'Shadow Mode.' The 2026 build (v1.5.0.726+) features full Windows 11 context menu integration and improved handling of large file commits to the real environment. It is ideal for testing suspicious software or managing public kiosks. While extremely reliable, the lack of centralized remote management makes it restrictive for large enterprise deployments.
