Can I remote desktop to multiple computers?


Due to my work, I need to remote into multiple computers at once. For example, in a mainframe room with 10 computers, I have to access each computer remotely to get my work done. Can I remote desktop to multiple computers?"

- Question from Tom

In today's digital age, the ability to access multiple computers remotely has become a necessity for many individuals and organizations. Whether you're a business owner, an IT professional, or a tech-savvy individual, the convenience and efficiency offered by remote desktop software are undeniable. But can you remote desktop to multiple computers simultaneously? Let's explore.

How to use Remote Desktop to remote into multiple computers [stepwise tutorial]

To remote into multiple computers for free, Remote Desktop (RDP) is a viable option. However, additional configurations are necessary. The following section will provide a comprehensive guide on configuring a Remote Desktop for simultaneous access to multiple PCs.

Part 1. Change the RDP port number in the Registry Editor

RDP default port 3389 only works for one computer, which means that if you want to connect to multiple computers at once, you must create a new port on each computer separately and then change the router accordingly to enable remote access to multiple computers. 

Step 1. Press Windows + R to and then type "regedit" to open the Registry Editor.

Run Box Regedit

Step 2. Navigation: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\ControlTerminal Server\WinStation\RDP-Tcp

Port Number

Step 3. Double-click on "PortNumber" in the right pane and tick "Decimal". The default port number is 3389, but you can change it to any other value, for example, 3388.

Change Port Number to 3389

✎ Note: Memorizing the port number corresponding to each computer for subsequent remote connections to multiple computers is necessary.

Part 2. Allowing the port to go through the firewall

After the setup of the port number for each PC, now we can allow the port to go through the Firewall so that we can connect successfully.

Step 1. Press Win + R and type "control panel" and hit “OK”.

Run Control Panel

Step 2. Click on “System and Security” and then find "Windows Defender Firewall". Click on “Advanced settings”.

Advanced Settings

Step 3. Double-click on "Inbound Rules" and then select "New Rule".

Step 6. Select "Allow the connection" in the "Action" screen, and click "Next". In the "Profile" screen, check the "Domain", "Dedicated" and "Public" options according to your needs and click "Next".

Confirm Check

Step 7. In the "Name" screen, enter the name of the new port, and click on "Finish".

Part 4. Connecting to the new port
