Answer 1

You can do by run a bat file:

@ECHO OFF                                                                              
FOR /F "tokens=5" %%T IN ('netstat -a -n -o ^| findstr "9797" ') DO (
SET /A ProcessId=%%T) &GOTO SkipLine                                                   
:SkipLine                                                                              
echo ProcessId to kill = %ProcessId%
taskkill /f /pid %ProcessId%
PAUSE

With Windows 10 default tools:

• Step one:

Open Windows PowerShell as Administrator

• Step two:

Find PID (ProcessID) for port 8080:

netstat -aon | findstr 8080

TCP 0.0.0.0:8080 0.0.0.0:0 LISTEN 77777

• Step three:

Kill the zombie process:

taskkill /f /pid 77777

where "77777" is your PID

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 can use PowerShell on Windows you just need :
