How to Change Remote Desktop Port in Windows 11

This guide explains how to change the remote desktop listening port in Windows 11.

When you use Remote Desktop to connect to your computer, it listens for a signal on a specific door, known as a port. By default, this is set to 3389. Because everyone knows this number, changing it can make your computer harder for strangers to find.

Why change the port? Changing this number adds a layer of security by hiding your connection from standard scans.

What happens when done? Your computer will stop listening on the old port and only accept connections through the new number you choose.
