Windows Kill Process By Port Number
In this short tutorial, we will look at how to kill a process by port number on Windows. I am doing a lot of Java development these days and I have about 5 different applications that I may fire up during a day and because they all run on my local machine most of them use port 8080 by default. Once in a while, I will forget to kill an application. When I try and start another application I will receive this error.
If you need to kill a process manually on Windows it's actually pretty easy. First, fire up a command prompt and type the following command.
> netstat -a -o -n
To kill the process we need to find the PID of the process in question. I just run down the list by port until I find port 8080 and here you will see the process id was 28344. Finally, with the PID we can run the following command to kill the process
taskkill /F /PID 28344
Pretty easy solution to a pretty simple problem. Hope this helps!
