|| 6to4, AudioSrv, Browser, CryptSvc, Dhcp, dmserver, EventSystem,
|| FastUserSwitchingCompatibility, lanmanserver, lanmanworkstation, Netman,
|| Nla, NtmsSvc, RasMan, Schedule, seclogon, SENS, SharedAccess,
|| ShellHWDetection, srservice, TapiSrv, Themes, W32Time, winmgmt, wscsvc,
|| wuauserv, WZCSVC.
Now I've done some research on the Web and found many websites that
services to keep automatic and which to disable or switch to manual. After abit
of trial-and-error I've pruned down my list of 27 services to 24:or so
AudioSrv, Browser, CryptSvc, Dhcp, dmserver, EventSystem,
FastUserSwitchingCompatibility, lanmanserver, lanmanworkstation, Netman,
Nla, NtmsSvc, RasMan, Schedule, seclogon, SENS, SharedAccess,
ShellHWDetection, srservice, TapiSrv, Themes, W32Time, winmgmt, wscsvc,
wuauserv, WZCSVC.
The ones I switched to manual or disabled are 6to4, seclogon, and TrkWks.
Result: the SVCHOST now seems to come up only about once every half hour
and stay for only about 1 or 2 minutes. This is a small but appreciated
improvement.
Do you see any other of these services that can be discontinued?

I think one of the best sites giving REASONABLE advice on the services issue is
www.eldergeek.com. There are quite a few that are unnecessary.
