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

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
