Is there a list of Services that Apps use. Like, what is the name of the service a certain app is running under so you can disable it?
Open command prompt and type "tasklist /svc" without the quotation marks. It'll list running processes and related services.
Can manage that with Autoruns - look at Services tab for relevant info and then right-click on that service and select Process Explorer. PE will open a service properties window where there are stop/restart buttons. Sysinternals Suite - http://technet.microsoft.com/en-us/sysinternals/bb842062.aspx
