how to remove windows service

SC STOP shortservicename
SC DELETE shortservicename

Note: You need to run the command prompt as an administrator, not just logged in as the administrator, but also with administrative rights. If you get errors above about not having the necessary access rights to stop and/or delete the service, run the command prompt as an administrator. You can do this by searching for the command prompt on your start menu and then right-clicking and selecting "Run as administrator". Note to PowerShell users: sc is aliased to set-content. So sc delete service will actually create a file called delete with the content service. To do this in Powershell, use sc.exe delete service instead

If you need to find the short service name of a service, use the following command to generate a text file containing a list of services and their statuses:

SC QUERY state= all >"C:\Service List.txt"
For a more concise list, execute this command:

SC QUERY state= all | FIND "_NAME"
The short service name will be listed just above the display name, like this:

SERVICE_NAME: MyService
DISPLAY_NAME: My Special Service
And thus to delete that service:

SC STOP MyService
SC DELETE MyService
