                         Query specific types of service.
          state= active|inactive|all

          group= groupname
                         Query services in a particular group.

   Misc commands that don’t require a service name:
          SC  QueryLock  Query the LockStatus for the ServiceManager Database.
                         This will show if a service request is running.
          SC  Lock       Lock the Service Database.
          SC  BOOT       Values are {ok | bad} Indicates whether to save  
                         the last restart configuration as the `last-known-good`
                         restart configuration.
   Options
     The CREATE and CONFIG commands allow additional service options to be set
     e.g. to disable a service: SC config "Name of Service" start= disabled
     see the built-in help for more: 'SC create' and 'SC config'

Note the qryOpt options above are case sensitive, they must be entered in lower case, also the position of spaces and = must be exactly as shown.

The SC command duplicates some aspects of the NET command but adds the ability to create a service.

Query a Service state

SC query will display if a service is running, giving output like this:

     SERVICE_NAME       : messenger
     TYPE               : 20  WIN32_SHARE_PROCESS
     STATE              : 4  RUNNING
                             (STOPPABLE,NOT_PAUSABLE,ACCEPTS_SHUTDOWN)
     WIN32_EXIT_CODE    : 0  (0x0)
     SERVICE_EXIT_CODE  : 0  (0x0)
     CHECKPOINT         : 0x0
     WAIT_HINT          : 0x0

To retrieve specific information from SC's output, pipe into FIND or FindStr
e.g.

  C:\> SC query messenger | FIND "STATE" | FIND "STOPPED"

  C:\> SC query messenger | FIND "STATE" | FIND "RUNNING"

The statements above will return an %ERRORLEVEL% = 1 if the text is not found

IF errorlevel 1 GOTO :my_subroutine

The NET START command can be used in a similar way to check if a service is running:

   NET START | FIND "Service name" > nul
   IF errorlevel 1 ECHO The service is not running

Watch out for extra spaces:
SC QUERY state= all Works
SC QUERY state =all Fails!

Start a Service

Start the schedule service:

SC start schedule

The service control manager will normally wait up to 30 seconds to allow a service to start, you can modify this time (30,000 milliseconds) in the registry

HKLM\SYSTEM\CurrentControlSet\Control
ServicesPipeTimeout (REG_DWORD)

Some options only take effect at the point when the service is started e.g. the SC config command allows the executable of a service to be changed. When the service next starts up it will run the new executable. Config changes requires the current user to have “permission to configure the service”.

PowerShell

Like every other external command SC can be run under PowerShell instead of CMD, however there is one extra complication for SC and that is the standard PowerShell alias SC which redirects to the Set-Content cmdlet.

To avoid that, use the call operator to run SC.exe from PowerShell:

& sc.exe

Examples:

 SC GetKeyName "task scheduler"
 SC GetDisplayName schedule 
 SC start schedule
 SC QUERY schedule
 SC CONFIG "Schedule" start= disabled
 SC QUERY type= driver
 SC QUERY state= all |findstr "DISPLAY_NAME STATE" >svc_installed.txt 
 SC \\myServer CONFIG myService obj= LocalSystem password= mypassword
 SC CONFIG MyService binPath=c:\myprogram.exe obj=".\LocalSystem" password=""

Disable Windows Update (Windows 10)

 SC config wuauserv start= disabled
 NET stop wuauserv

 SC config bits start= disabled
 NET stop bits

 SC config dosvc start= disabled
 NET stop dosvc

To re-enable Windows Update set the start= back to auto and start the services.

Enable remote registry access on computer64:

 SC \\computer64 config remoteregistry start= auto
 SC \\computer64 start remoteregistry
