[Service Name] Application Layer Gateway Service [Recommended Setting] Manual [Notes] 
Used for Assign Publish and Remove software services. Some users have emailed me and have told me that their computer needs this service. I have it disabled, and I'm doing fine. You should set this to manual, and if an application needs this service, it will start, otherwise it will not.
