www.BlackViper.com: Windows XP Service Pack 2 Services 411 - COM+ System Application

COM+ System Application

Default Description:

Manages the configuration and tracking of Component Object Model (COM)+-based components. If the service is stopped, most COM+-based components will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

You will receive, in the Event Log, an entry from "DCOM" complaining about not having this service running if disabled. I am unaware of any application that uses COM+, but if set to manual, many services report to it, so it will start anyway. For the fun of it, check:

"C:\Program Files\ComPlus Applications"

On your system, see if you have any installed "COM+" Applications. If not, you can probably disable this service with no side effects (besides the Event Log complaining upon reboots). This service is required for System Event Notification.
