If you are pushing it via GPO there is a chance it is not working. Setting the startup type to Automatic does not work in Pref’s, you will see the GPO denied in your event log. You have to regedit it to Automatic, and also delete the TriggerInfo key to remove the trigger restriction.
At this point, I am not getting any message when it blocks something. No pop up telling the user what happened as it did in Win 7.
