n2fc has got the right of it.  So far as I know, the only way to permanently delete a service is less than safe:

  • Use Autoruns or msconfig to remove its startup run entry
  • Edit the Registry.  Since Services appears in every control set, it's easy to overlook occurrences.

You can use the sc utility to remove a service. You'll need to know the internal service name. not the display name:
sc stop YourService
sc delete YourService

The question isn't about disabling a service, but removing it, so the first comment does not apply.

My comment is correct and a solution.

Dr. Klahn's comment is correct in most parts: msconfig does not remove, but move the service entries to a different registry path. Same for AutoRuns if you uncheck the service (instead of removing). Superficially that is "the same" as removing the service, as it does not appear in the service manager anymore.
AutoRuns indeed allows to remove the service permanently, so this is an answer.

The registry edit is a valid solution, too, but you only need (and should) care about CurrentControlSet and leave the other ControlSetXXX keys as-is.
