Controls Windows services, supporting starting, stopping, querying and more.
A Windows service is a a program running in the background. A service is either hosted in its own process or it is hosted in an instance of svchost.exe process, often with multiple services in the same instance.
Processor time use of a particular service can be found using freely downloadable Process Explorer from Sysinternals, by going to properties of a service and then Threads tab.
sc start wuauserv
Starts wuauserv service.
sc stop wuauserv
sc query wuauserv
Outputs information about all services.
sc config SysMain start= disabled
Make sure SysMain service is disabled after start. SysMain is the SuperFetch service, causing repeated harddrive activity by trying to guess which programs to load into RAM in case they will be used, and loading them. Notice the mandatory lack of space before = and the mandatory space after =.
