description: This rule identifies attempts to create or rename the registry key HKLM\SYSTEM\CurrentControlSet\Control\MiniNt. Adding this key can disable Windows event logging after a reboot, which matters to attackers seeking defense impairment by reducing available audit telemetry. It relies on registry event telemetry capturing key creation and rename activity, including the target object or the new registry key name.
