Steps in tutorial:
1. Find process using the port number
Go to Windows search box and type CMD. Right-click on Command Prompt and Run it as administrator

Type command:
netstat -aon | findstr (Port Number)

Replace the Port Number, with the actual port number that you want to check, hit enter.
If the port is being used by any application, then that application’s detail will be shown in the list.
The number, which is shown at the last column, is the PID number, the process ID of that application.
Now you can find application name, using PID number

Type command:
tasklist | findstr (PID Number)

Replace the PID Number with the number from the list, that you want to check and hit enter.

2. Check which application is using which port, with two different methods.
Remember that the Command prompt must be run as an administrator
This command displays the entire list with details, which application is using which port number:
netstat –a –b –n –o

You can find command meaning by typing:
netstat /?
-a, displays all connections and listening ports.
-b, displays the executable involved in creating each connection listening port.
-n, displays addresses and port numbers in numerical form.
-o, displays the owning process ID associated with each connection.

The second method to check which application is using which port number:
Go to Windows search box and type resmon, (resource monitor)
Go to Network tab
Open the Listening Ports sidebar
There you can find a list of all listening ports that are used by different applications

How can I link a specific USB device, eg pointer, to a specific USB port while allowing all other running applications linked to the USB wireless mouse? Example: a PowerPoint presentation that will only respond to the USB pointer while other apps respond to the mouse.

Hi mmk and thank you for the video. I found that the "System" process (PID=4, is using port 80, but it could not be stopped, so I can not start my IIS website on Windows Server 2019 (my website is started and worked well before). Do you know the way to stop it and disable it for me to start my website in IIS with port 80 (I don't like to use other ports). Thanks!
