How to change the default RDP port in Windows


Remote Desktop Protocol is used by Windows users to connect remotely to another computer. By default, the RDP port is 3389 and sometimes you may want to change this port and assign another port for the RDP.

In this guide, we will be using the Registry Editor to make the changes to the RDP port, but you have to be very careful when you are using the Registry Editor because if not handled properly can cause permanent damage to the system.

But why do we want to change the default RDP port? Everyone knows that Microsoft uses the standard port 3389 for all remote connections and this is to the bad actor’s advantage because they are always trying to access people’s systems without their knowledge. So changing this default port to another open port will make it very hard for an attacker to easily break into your system.

  1. Open the Registry Editor
Registry Editor

You can also run the regedit command.


2. Browse to this key KEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Registry Editor

3. Click on the PortNumber and click Decimal option button. In the Value data field enter the new port number and click OK to save the changes. In this guide I will be changing 3389 to 3333.

Editing PortNumber

You can confirm if the port have actually been changed using this command on PowerShell.

Get-ItemProperty -Path ‘HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp’ -name “PortNumber”

Run it on Windows PowerShell and you will see the RDP Port has now changed to 3333

Another thing you will need to do is to open the ports because if you try to RDP using this port may not work at first until you open it.

If you would like to see a live demonstration of how this can be done, I have embedded a YouTube video beneath.
