Karn, just use the tool INSTSRV.EXE, Find it and download it to ur SYSTEM32 folder..
Then type the command,
INSTSRV <SERVICENAME> REMOVE
Will completely remove the service... Dont forget to stop the SERVICE before you try to delete it, That will only help you...
Hope that your problem solved... If you want alternate solution, I can help you...
