( string servicename [, string machine] )
Attempts to delete a service from the SCM database. Administrative
privileges are required for this to succeed.
This function really just marks the service for deletion. If other
processes (such as the Services Applet) are open, then the deletion will be
deferred until those applications are closed. If a service is marked for
deletion, further attempts to delete it will fail, and attempts to create a
new service with that name will also fail.
