Re: Unregistering a Service
First, stop and disable the service. The fact that the service is running (if it's running) means that the DLLs are still there.
Open up REGEDIT, head over to HKLM/system/currentcontrolset/services
And look for your service. Navigate a bit there and look for some files which it may be referring to. Delete the registry key and delete those files, then reboot the machine.
I am not responsible if your computer explodes.
