Ever wondered what the multiple svchost.exe or other generic process listed in Windows XP's task manager are used for? Next time you need to stop or restart a stalled process try this: Open the command prompt by typing "cmd" from the "start/run" window. In the command prompt type "tasklist /svc". This will list your processes and the programs that are using them.
In Vista or Windows 7 it's much simpler. Go to the Task manager, right click on the process, and click "go to services". This will detail which programs are being used by the particular service.
