[B]Nvidia Display Driver Service[/B]
This service generally doesn't have an essential function. In my experience, most people can
safely disable it and not run into any difficulties or reduced functionality whatsoever. In fact
some users note that disabling this service improves Windows startup and shutdown times
and general performance. However, some people report potential issues with temperature
monitoring on their graphics cards if this service is disabled. In general if you feel you are
experiencing any other strange behavior due to the disabling of this service, set it back to
Automatic and restart it. Note: In Vista, the Nvidia Display Driver Service is actually a startup
item called NvSvc, not a service, but the same description applies.
