By default, Windows uses TCP/IP port 3389 for remote desktop connection. Since this port is well known and it could pose a security risk, you’d better change remote desktop RDP port for your Windows computer as an added security measure. The following method works with Windows 10, 8, 7 and Windows Server.

How to Change RDP Port for Windows Remote Desktop Connection?

1. Press the Windows + R keys to open the Run command box. Type regedit and press Enter.

   

2. On the left-side of Registry Editor, navigate to the following key:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber

   

   Scroll down on the right until you see the PortNumber value, and then double-click it to modify.

3. Click Decimal, and type in the new port number that you want to use for remote desktop and click OK.

   

4. Close the Registry Editor and reboot the computer. Note that the next time you connect to your PC with RDP you will need to add a colon followed by the port number to the IP address.

   

That’s it!
