kill a process running on a specific port in Windows

 

Step 1: Find the PID (Process ID) using the port

Open Command Prompt (CMD) as Administrator and run:

netstat -aon | findstr :<PORT>

Replace <PORT> with the actual port number you're targeting.

📌 Example (for port 5000):

netstat -aon | findstr :5000

Look for a line like:

  TCP    0.0.0.0:5000           0.0.0.0:0              LISTENING       1234

The last number (1234 in this example) is the PID.

---

🧨 Step 2: Kill the process by PID

Once you have the PID, run:

taskkill /PID <PID> /F

Replace <PID> with the number from the previous step.

📌 Example:

taskkill /PID 1234 /F


Make a batch Script

Option 1: Batch Script (Simple & Quick)
You can save the following as kill_port.bat and run it as Administrator:
---------------------
@echo off
set /p PORT=Enter port number to kill: 

for /f "tokens=5" %%a in ('netstat -aon ^| findstr :%PORT%') do (
    echo Killing process with PID %%a
    taskkill /PID %%a /F
)
pause

-------------------------------------
How to Use:
Open Notepad.
Paste the script above.
Save as kill_port.bat (use Save as type: All Files).
Right-click it and choose Run as Administrator.

Option 2: PowerShell Script (More Robust)
------------------------------------------------------------------------------
$port = Read-Host "Enter port number"
$connection = netstat -aon | Select-String ":$port"

if ($connection) {
    $pid = ($connection -split '\s+')[-1]
    Write-Host "Killing process with PID $pid"
    Stop-Process -Id $pid -Force
} else {
    Write-Host "No process found using port $port"
}


-------------------------------------------------------------------------------
How to Use:
Save it as Kill-Port.ps1.
Run it from PowerShell as Administrator.
