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

COM+ Event System

Default Description:

Supports System Event Notification Service (SENS), which provides automatic distribution of events to subscribing Component Object Model (COM) components. If the service is stopped, SENS will close and will not be able to provide logon and logoff notifications. 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. This service is required for System Event Notification. 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). Take note: BootVis requires Task Scheduler and COM+ Event System to be running if you wish to take advantage of the "optimize system" function. Why is it required? It is due to the pre-fetching function built into Windows XP. Another Note: Pre-fetching only occurs on boot up and application start, so if you do not care about a few extra seconds of boot time, you may decide to not even bother with it and disable Task Scheduler. However, depending on the system and what applications are being used, pre-fetching may increase performance. Windows Media Player may also require this service for some "features" to function. MS' .NET may require this service in the future.
