And there's this: "A service is an application that runs in the background, independent of any user session. It is not unlike the daemon processes one hears about on Linux. Microsoft currently defines services as: ?An executable object, installed in a registry, maintained by the Service Control Manager. The executable file associated with a service can be started at boot time by a boot program, or on demand by the Service Control Manager?. Many of the service names have been intercepted by the MS-marketing folks, so sometimes it's easier to refer tothe service by its short name." from this site:

svchost.exe: "You'll notice that many of the services run under the same executable, svchost.exe. This is a generic program that DLL-based services can be run from, gathering additional parameter values (like, which service to actually run) from the registry. Thus, if a DLL is listed under the Executable column, it's started from svchost.exe."
