There is a command like this in windows
1) netstat -ano to view all processes occupying ports in the operating system
eg: netstat -ano | findstr " 8081 " to get the process that occupies port 8081
The latter is the binding IP and port, and the last column is the occupied process number (pid)
2)taskkill /pid 123
We can close the process whose process number is 123. Of course, when I tried the above command, the system prompts that the process cannot be terminated, then we can add a /F, as follows, to forcibly close it.
taskkill /F /pid 123
