I can't find a setting to disable WINS in Network settings

In my Network settings under WINS I have the NetBios name (elly) that I
would like to disable (kill).
The message shows that the "elly"is currently been used ?
By whom, for what ?
There a bunch of messages in the Console with for example elly.local
WindowServer ?? what server ? I do not have one ?
My search on Google and here did not help.
I tried deleting the NetBios name, but it comes back!
Also tried the without success!
sudo launchctl unload -w
/System/Library/LaunchDaemons/com.apple.netbiosd.plist
I have no local network, nor any workgroup set up, just a lone wifi
connection to the world.
Running Hostname in Terminal shows "Elly.Local"
I would not mind using Terminal to kill it, but I'm just wondering whether
there's any UI-based way to just turn off all of this stuff. I am not a
big fan of running services I'm not using.
