There will be a PID number listed on the same line you're looking at. That is a Process Identification Number, and you can use it to see which program on your computer has the open connection. To cross-reference, open Task Manager and go to the processes tab. You may need to tell Task Manager to display the PID column if it's not already there. To do so, click View -> Select Columns, and check the PID box. Then look in Task Manager for the process with the same PID number. That process will be the one with the open listening port.



It's important to note that "listening" is a normal port state. It means an application is waiting for communication. If the application is one you've never heard of, let us know what the process name is, and we might be able to provide additional insight.
