This policy setting allows you to enable real-time definition updates in response to reports sent to Microsoft Active Protection Service (MAPS). If the service reports a file as an unknown and MAPS finds that the latest definition update has definitions for a threat involving that file, the service will receive all of the latest definitions for that threat immediately. You must have configured your computer to join MAPS for this functionality to work.
If you enable or do not configure this setting, real-time definition updates will be enabled.
If you disable this setting, real-time definition updates will disabled.
