After several Hours with 4 Windows Techs...
I had a laundry list of problems including no sound, no backup, no internet
, no ready boost, no security, etc... after an aborted program installation and a bad Windows shutdown
If you can, create a restore point before proceeding.
for additional information about services settings.
There are at least 3 component services required for recognition of hardware and drivers
for internet access and several more for security software and security monitoring to operate!
Start---execute on command line "service.msc"
Component Services---Services (local) [maximize window]
Inspect the list of component services (screens of them). Select disabled services one-by-one, reset Startup Type
to "automatic" (a few won't allow this or will reset properly at reboot). You can attempt to start each service as they are activated (some are dependent on other services, view with tab of dialog) or reboot after all are activated.
I had about 3/4 of the services disabled. Took about 3/4 hour to reactivate. Results were pleasing to the eye and effort!
