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.
Another command capable of controlling services is NET. TASKLIST can list hosted services using
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 =.

Further options do not apply in this case. If the query command is followed by nothing or one of the options listed below, the services are enumerated. type= Type of services to enumerate (driver, service, userservice, all) (default = service) state= State of services to enumerate (inactive, all) (default = active) bufsize= The size (in bytes) of the enumeration buffer (default = 4096) ri= The resume index number at which to begin the enumeration (default = 0) group= Service group to enumerate (default = all groups) SYNTAX EXAMPLES sc query - Enumerates status for active services & drivers sc query eventlog - Displays status for the eventlog service sc queryex eventlog - Displays extended status for the eventlog service sc query type= driver - Enumerates only active drivers sc query type= service - Enumerates only Win32 services sc query state= all - Enumerates all services & drivers sc query bufsize= 50 - Enumerates with a 50 byte buffer sc query ri= 14 - Enumerates with resume index = 14 sc queryex group= "" - Enumerates active services not in a group sc query type= interact - Enumerates all interactive services sc query type= driver group= NDIS - Enumerates all NDIS drivers
