Stepwise Tutorial on Remote Desktop Multiple Sessions in Windows 10, 11

Can Windows 10 support multiple RDP sessions?

We are sorry to tell you that Windows 10 can’t support multiple RDP sessions, which means Windows Pro and Enterprise editions (Home editions is incompatible) are allowed to set up the Remote Desktop Connections via RDP in only one single remote session. Only Windows Server OS supports multiple RDP connections up to 2 sessions per license for free.

If a second user tries to establish an additional session, a pop-up warning will appear asking whether to cancel the connection or close the previous session.

How to enable Remote Desktop multiple sessions Windows 10, 11 [2 options]

No way for Remote Desktop multiple sessions Windows 10/11? Not exactly. Although Microsoft’s policy towards multiple Remote Desktop sessions is to purchase CALs to enjoy more rights, in theory, computer resources are the only factor to allow Remote Desktop multiple connections (an average of 150-200 MB of memory is required per user session). Therefore, you still have ways to enable Windows multiple users simultaneously. And in this part, we offer 2 options for you to choose from.

Option 1. Use RDP Wrapper to achieve multiple Remote Desktop sessions

Utilizing the RDP Wrapper, which serves as a layer between the Remote Desktop Service and Service Control Manager, is one way to enable Windows multiple RDP sessions. It doesn't alter the termsrv.dll file, and this application will continue to operate if Windows is upgraded.

Ensure that the termsrv.dll file you are using is the original version before doing any operations.

Step 1. Download the latest available version of the RDP Wrapper Library from GitHub.

Step 2. Then you can find the following files in the RDPWrap-v1.6.2.zip archive:

• RDPWinst.exe(RDP Wrapper Library installation/uninstallation program).
• RDPConf.exe(RDP Wrapper configuration utility).
• RDPCheck.exe(Local RDP Checker, RDP check utility).
• install.bat, uninstall.bat, update.bat(batch files for install, uninstall, and updates for RDP Wrapper).

Step 3. Find and right-click the install bat, and select Run as administrator in the context menu to install RDPWrap.

Step 4. The program will be installed to the C:\Program Files\RDP Wrapper directly, once the installation is complete, you can see the successfully installed information below.

Step 5. Open the RDPConfig.exe to check whether the RDP Wrapper is running, and make sure all elements are green in the Diagnostics section.

Most likely, immediately after installation, the tool will show that the RDP wrapper is running (Installed, Running, Listening), but not working, which is reported by the red warning [not supported].

Step 6. Manually copy and paste the contents of the following page to the C:\Program Files\RDP Wrapper\rdpwrap.ini file.

https://raw.githubusercontent.com/sebaxakerhtc/rdpwrap.ini/master/rdpwrap.ini

Step 7. Restart your computer. Run RDPConfig.exe tool to check all the items are green in the Diagnostics section and the caption [fully supported] appears.

Step 8. Run the RDPCheck.exe and try to establish multiple RDP sessions on your computer. Now you are able to perform Remote Desktop multiple sessions Windows 10/11.

Option 2. Enable Remote Desktop multiple sessions by modifying the Termsrv.dll

You can also achieve Windows 10 multiple users simultaneously via RDP by editing the original Termsrv.dll file.

Before operations, download the zipped patch file based on your Windows versions.

Step 1. To launch the Services management interface, press Win + R and enter “services.msc” . Find and right-click Remote Desktop Services in the context menu and then click Stop.

Step 2. We recommend you to open Command Prompt as administrator and enter the following command to back up the original termsrv.dll file.

copy c:\Windows\System32\termsrv.dll termsrv.dll_old

Step 3. Change the values of the following keys in HKLM> System> CurrentControlSet> Control> Terminal Server:

• fDenyTSConnections (DWORD) — 0
• fSingleSessionPerUser (DWORD) — 0

You can also do it quickly by entering the following two command lines in the Command Prompt:

• REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fDenyTSConnections /t REG_DWORD /d 0 /f
• REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fSingleSessionPerUser /t REG_DWORD /d 0 /f

Step 4. Navigate to C:\Windows\System32 to find and right-click the termsrv.dll file, and then select Properties.

Step 5. Click Change to change the file owner from “TrustedInstaller” to a local administrators group.

Step 6. Click Edit on the Security tab. Select the local administrators group and give it Full control over this file and then click OK.

Step 7. Copy the termsrv.dll file from the archive downloaded before operations and replace it with the original one in %SystemRoot%\System32\.

Step 8. Open the Services management console again to start the Remote Desktop Services.

And now you can establish two multiple RDP sessions.
