Windows Error Reporting Service

Vista Basic sp2

I have Windows Error Reporting Service Disabled in Services.

But, in Task Scheduler the Windows Error Reporting is still

set to and does run at "Log on of any user."

I thought disabling the service in services causes the service not to run!?

Any idea why this runs even though I have the service disable??

The only reason I found out this runs is because I have an event sound for

Open Program.

I wonder how many other services I have disabled that run without my

knowledge.

Thanks

James
