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

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 :<PORT>

(Replace <PORT> 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 <PID> /F

(No colon this time)

Lastly, you can check whether the operation succeeded or not by re-running the command in "Step 1". If it was successful you shouldn't see any more search results for that port number.

Answer 2

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

Answer 3

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 4

There are two ways to kill the processes

Option 01 - Simplest and easiest

Requirement : [email protected]^ version

Open the Command prompt as Administrator and give the following command with the port (Here the port is 8080)

npx kill-port 8080

---

Option 02 - Most commonly used

• Step 01
  
  Open Windows command prompt as Administrator
• Step 02
  
  Find the PID of the port you want to kill with the below command: Here port is 8080

netstat -ano|findstr "PID :8080"

TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 18264

• Step 03
  
  Kill the PID you received above with the below command (In my case PID is 18264)

taskkill /PID 18264 /f
