Discussion

This policy setting configures a local override for the configuration of behavior monitoring. This setting can only be set by Group Policy. If this setting is enabled, the local preference setting will take priority over Group Policy. If this setting is disabled or not configured, Group Policy will take priority over the local preference setting.
