Service Control – Create, Start, Stop, Query or Delete any Windows SERVICE. The command options for SC are case sensitive.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 |
Syntax SC [\\server] [command] [service_name] [Options] Key server : The machine where the service is running service_name : The KeyName of the service, this is often but not always the same as the DisplayName shown in Control Panel, Services. You can get the KeyName by running: SC GetKeyName <DisplayName> commands: query [qryOpt] Show status queryEx [qryOpt] Show extended info - pid, flags GetDisplayName Show the DisplayName GetKeyName Show the ServiceKeyName EnumDepend Show Dependencies qc Show config - dependencies, full path etc start START a service. stop STOP a service pause PAUSE a service. continue CONTINUE a service. create Create a service. (add it to the registry) config permanently change the service configuration delete Delete a service (from the registry) control Send a control to a service interrogate Send an INTERROGATE control request to a service Qdescription Query the description of a service description Change the description of a service Qfailure Query the actions taken by a service upon failure failure Change the actions taken by a service upon failure sdShow Display a service's security descriptor using SDDL SdSet Sets a service's security descriptor using SDDL qryOpt: type= driver|service|all Query specific types of service state= active|inactive|all Query services in a particular state only bufsize= bytes ri= resume_index_number (default=0) 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:
1 2 3 4 5 6 7 8 |
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.
1 2 3 |
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:
1 2 |
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:
1 |
& sc.exe |
Examples:
1 2 3 4 5 6 7 8 9 |
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)
1 2 3 4 5 6 7 8 |
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:
1 2 |
SC \\computer64 config remoteregistry start= auto SC \\computer64 start remoteregistry |
That means you’ll lead some new features and from access to additional channels where you can pick up visibility, without having to designate sense of some elaborate, guide migration process.
I have fun with, lead to I found just what I used to be
looking for. You have ended my four day lengthy hunt!
God Bless you man. Have a great day. Bye
Wonderful blog! I found it while surfing around on Yahoo News. Do you have any suggestions on how to get listed in Yahoo News? I’ve been trying for a while but I never seem to get there! Many thanks
I adore reading and I conceive this website got some truly useful stuff on it! .
