[Service Name] COM+ Event System [Recommended Setting] Disable [Notes] 
I could not find a lot of information about COM+ Event System but here is what I found at Microsoft's site: The COM+ Events service uses an event class object to manage the connection between publisher and subscriber. The event class object is a COM+ component that is managed and stored by the COM+ Events system and contains the interfaces and methods used by a publisher to fire events. It is a persistent object that indicates the events that can occur and, optionally, identifies the publisher. You specify the interfaces and methods you want an event class to contain by providing a type library.
