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

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.

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

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
