What it detects

This rule flags a registry value change that sets UseActionCenterExperience to 0 under Windows\CurrentVersion\ImmersiveShell\, which disables Windows Security Center notification behavior. Attackers can use this to reduce user visibility into security-related alerts and degrade defensive awareness. The detection relies on registry set telemetry capturing the TargetObject path and the DWORD value being written.
