Hello Frank.
I've just been all through the list of services in Vista Ultimate and it is not listed there either, the closest is the one highlighted in the snip below, both in Vista and Windows 7.
The best way to handle the services in Windows 7 and Vista for that matter, is to let the system manage the services, it's a whole 'nother animal from XP and they don't need micro-managed like XP did, in fact you may cause Windows 7 to run exceptionally slower if some services are changed from their default setting.
