Is there a way to identify what services are using the cpu power?

look at the attached image, i want to know what service is usint the high percentage of cpu power - any ideas? the ud_ligfit_release.exe is a distribured computing program.

 

Open up a DOS window and type tasklist /svc it gives you a list of running services, including those controlled by svchost.exe.

If memory serves, that is the Yahoo Pager. A ridiculous little service they bundle in with Yahoo messenger. I always removed it and never had any trouble using Yahoo although I don't use that any longer either.

 

Yup, I was right again. Just googled 'Ypager.exe' and found this.
