I was running zookeeper on Windows and wasn t able to stop ZooKeeper running at 2181 port using zookeeper-stop sh  so tried this double slash      method to taskkill  It worked       1  netstat -ano   findstr  2181        TCP    0 0 0 0 2181           0 0 0 0 0              LISTENING       8876        TCP         2181                   0                 LISTENING       8876       2 taskkill   PID 8876   F        SUCCESS  The process with PID 8876 has been terminated

If you re using Windows Terminal then the killing process might be little less tedious  I ve been using windows terminal and kill PID works fine for me to kill processes on the port as the new Windows Terminal supports certain bash commands  For example  kill 13300 So  the complete process will look like this-  Open Windows Terminal Type the following command to show processes running on the port you re looking to kill processes  netstat -ano   findstr  PORT Type following to kill the process  kill PID  For Example  PS C  Users username gt  netstat -ano   findstr  4445   TCP    0 0 0 0 4445           0 0 0 0 0              LISTENING       7368   TCP         4445                   0                 LISTENING       7368 PS C  Users username gt  kill 7368 PS C  Users username gt  netstat -ano   findstr  4445 PS C  Users username gt   See when I typed the first command to list processes on the port it returned empty  That means all processes are killed now  Update  kill is an alias for Stop-Process  Thanks   FSCKur for letting us know

Step 1  Open up cmd exe  note  you may need to run it as an administrator  but this isn t always necessary   then run the below command   netstat -ano   findstr   lt PORT gt    Replace  lt PORT gt  with the port number you want  but keep the colon   The area circled in red shows the PID  process identifier   Locate the PID of the process that s using the port you want  Step 2  Next  run the following command   taskkill  PID  lt PID gt   F   No colon this time   Lastly  you can check whether the operation succeeded or not by re-running the command in  quot Step 1 quot   If it was successful you shouldn t see any more search results for that port number

In case you want to do it using Python  check Is it possible in python to kill process that is listening on specific port  for example 8080   The answer from Smunk works nicely  I repeat his code here   from psutil import process iter from signal import SIGTERM   or SIGKILL  for proc in process iter        for conns in proc connections kind  inet            if conns laddr port    8080              proc send signal SIGTERM    or SIGKILL             continue
