Check open port for program in Windows

Open your command prompt and type in netstat -ano this will list all processes ID and what port it is running or listening on.

Find the port you’re inquiying about and take note of the PID. Now that you have the PID number (located to the left side of the command prompt) you can open up the task manager to tie that PID to a process / program.

Just hit Control + Alt + Del to open Task Manager. Once Task Manager is open you need to display the PID by;
Click tab Process > Click menu View > Click menu Select Columns.. and then select PID (Process Identifier).

Now you can see the PID and the corresponding program / process associated with it.
