Shadow Defender is a commercial security utility that provides system-level protection by running Windows in a virtualized “shadow mode,” redirecting changes to a temporary layer so the underlying system remains unchanged after a reboot. While Shadow Defender can be useful on desktop and single-purpose machines to prevent persistent malware, its use, licensing, and deployment raise important technical and administrative considerations for server environments such as Internet Information Services (IIS) on Windows Server 2021.
Shadow Defender 1.4.0.680 is an older stable release of the lightweight virtualization security tool, originally launched on May 8, 2018.
