BatchPatch can control and monitor in real-time an update process that is triggered with BatchPatch. It cannot control and monitor an update process that is triggered by Group Policy. You can, however, have GPO download the updates but then have BP trigger the installation process. For that please refer back to the link in my previous posting.
If you have GPO setup to do the entire process but you want to prevent the installation after updates have already been downloaded then you would need to modify the GPO.
