Any free ways to remote into 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. What should I do now to access multiple computers remotely? It’s better to be free.}

How to use Remote Desktop to remote into multiple computers [extra setup]

To remote into multiple computers free, we can use Remote Desktop (RDP). We need some extra settings. In the next part, a detailed description of how to set up Remote Desktop for remoting into multiple PCs at once will be demonstrated.

Part 1. Change the RDP port number in 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 could 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 4. Select "Port" in the "Rule Type" screen, and click "Next".


Step 5. In the "Protocol and Port" screen, select "TCP", enter the port number, such as 3327, and click "Next".


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".

✎ Note: The operation of changing the RDP port needs to be done on each remote computer separately.

Part 3. Assigning ports through the router

Step 1. Open the router configuration interface and find the Single Port Forwarding section.

Step 2. Enter the port number used to identify the computer or registry changes. For example, Desktop for the local computer and Laptop and Joe's PC for other remote computers.

Change Port Number

Step 3. We also need to find the IPv4 address of each computer and assign it to the corresponding port number. Press "Win + R" and type "cmd", hit “OK”, and type "ipconfig" to find the computer's local IP address of the computer.

Find the IP Address

Part 4. Connecting to the new port

Now the setup is completed, you can connect to the object users one by one. But it needs to be mentioned that you should change the port number every time you connect to another user.

Step 1. Search "Remote Desktop Connection" in the search box.

Remote Desktop Conenction

Step 2. In the "General" tab, enter the IP address and user name of the host computer, and then click "Connect".

Label the Port Number

Step 3. In the Windows Security pop-up window, enter the password under this user name and click "OK".

Step 4. Click "Yes" for the Authentication pop-up window to successfully establish a remote connection. After that, you can remote into multiple computers in turn.
