I cannot find a service with that name. During a fit of temporary
insanity I may have turned the service or services off. Any Ideas?

That service exists when I use services.msc on Windows 7 Home x64. I
wouldn't think this is an edition-specific service; i.e., it should be
present in each edition of Windows 7. Where did you look to find the
service? Turning off a service or disabling it does not remove it.
