How do I kill the process currently using a port on localhost in Windows?

Question

How can I remove the current process/application which is already assigned to a port?

For example: localhost:8080

Answer 1

I know that is really old question, but found pretty easy to remember, fast command to kill app that are using port.

Requirements: npm@5.2.0^ version

npx kill-port 8080

You can also read more about kill-port here: https://www.npmjs.com/package/kill-port

Answer 2

If you are using GitBash

Step one:

netstat -ano | findstr :8080

Step two:

taskkill /PID typeyourPIDhere /F 

(/F forcefully terminates the process)

Answer 3

the first step

netstat -vanp tcp | grep 8888

example

tcp4     0      0    127.0.0.1.8888   *.*    LISTEN      131072 131072  76061    0
tcp46    0      0    *.8888           *.*    LISTEN      131072 131072  50523    0

the second step: find your PIDs and kill them

in my case

sudo kill -9 76061 50523

Answer 4

Step 1 (same is in accepted answer written by KavinduWije):

netstat -ano | findstr :yourPortNumber

Change in Step 2 to:

tskill typeyourPIDhere 

Note: taskkill is not working in some git bash terminal

Answer 5

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

For Windows users, you can use the CurrPorts tool to kill ports under usage easily:
