What it detects

This rule flags registry modifications that set specific Windows policy keys to values consistent with disabling system tools, restricting functionality, or impairing user interface elements. Attackers may use these registry changes to hinder defense and user response by reducing visibility and functionality, leveraging Windows policy-based controls. It relies on telemetry from registry set events capturing the TargetObject and the set Details value (DWORD 0x00000001 or 0x00000000) for the matched policy paths.
