Under Windows, if you have the message "port already used by the system", you can use this command to determine and stop the blocking process or program :

netstat -ab use to display the already used ports and the executable associated (could be [system]).

netstat -o will display the process PID associated with ports mapping.

Taskkill /PID XXXX /F can force a process or program to stop.
