How can I delete a service in Windows?

I have a couple old services that I want to completely uninstall. How can I do this?

From stackoverflow

• this has nothing to do with programming. . .

  Eric Z Beard : System administration questions are Ok. Programmers constantly deal with these kinds of issues.

  Mostlyharmless : Not specifically the question, but whoever does a lot of windows programming will find the answer useful. I for one need to do those a lot when debugging / testing my COM+ app.

• Click Start | Run and type regedit in the Open: line. Click OK.

  Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

  Scroll down the left pane, locate the service name, right click it and select Delete.

  Reboot the system

• Remove the right key from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\

• Use the SC command, like this (you need to be on a command prompt to execute the commands in this post):

  SC STOP shortservicename
  SC DELETE shortservicename
  

  If you need to find the short service name of a service, use the following command to get a list of services and their status:

  SC QUERY
  

  For a more concise list, execute this command:

  SC QUERY | FIND "_NAME"
  

  The short service name will be listed just above the display name, like this:

  SERVICE_NAME: SSDPSRV
  DISPLAY_NAME: SSDP Discovery Service
  

  And thus to delete that service (it is not recommended to delete the SSDPSRV service btw):

  SC STOP SSDPSRV
  SC DELETE SSDPSRV
  

  sgwill : Why do you not recommend that?

  Lasse V. Karlsen : Deleting the SSDP Discovery Service? It is used for detecting and configuring UPnP devices on the local network, you should not delete it. It was just used as an example.

  sgwill : Oooh, I see, yes. I thought you meant deleting services wasn't recommended. Thanks for the answer!

• sc delete name

• Use services.msc or (Start > Control Panel > Administrative Tools > Services) to find the service in question. Double-click to see the service name and the path to the executable.

  Check the exe version information for a clue as to the owner of the service, and use Add/Remove programs to do a clean uninstall if possible.

  Failing that, from the command prompt:

  sc stop servicexyz
  sc delete servicexyz
  

  No restart should be required.

• Here is a vbs script that was passed down to me:

  Set servicelist= GetObject("winmgmts:").InstancesOf ("Win32_Service")

  for each service in servicelist

  sname=lcase(service.name)

  If sname = "NameOfMyService" Then

      msgbox(sname)
      service.delete ' the internal name of your service
  

  end if

  next

• If they are .NET created services you can use the installutil.exe with the /u switch its in the .net framework folder like C:\Windows\Microsoft.NET\Framework64\v2.0.50727
