   Options
     The CREATE and CONFIG commands allow additional options to be set
     see the build-in help: '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.
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

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”.

Examples:

 SC GetKeyName "task scheduler"
 SC GetDisplayName schedule 
 SC start schedule
 SC QUERY schedule
 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=""  

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