Multiple RDP on Windows 10/11

RDP Wrapper: Enable Multiple RDP Sessions on Windows

The RDP Wrapper Library OpenSource project allows you to enable multiple RDP sessions on Windows 10 without replacing the termsrv.dll file. This tool works as a layer between SCM (Service Control Manager) and the Remote Desktop Services. RDPWrap allows you to enable not only support for multiple simultaneous RDP connections but also to build an RDP server on Windows Home editions. RDP Wrapper doesn’t make any changes to the termsrv.dll file, it’s just loading termsrv library with the changed parameters.

Thus, the RDPWrap will work even in the case of termsrv.dll file update. It allows you not to be afraid of Windows updates.

Important. Before installing RDP Wrapper, it is important to make that you are using the original (unpatched) version of the termsrv.dll file. Otherwise, RDP Wrapper may become unstable or not start at all.

You can download the RDP Wrapper from the GitHub repository (the latest available version of the RDP Wrapper Library is v1.6.2). The project hasn’t been updated since 2017, but it can be used in all new builds of Windows 10 and even Windows 11.

The archive contains some files:

  • RDPWinst.exe — an RDP Wrapper Library install/uninstall the program;
  • RDPConf.exe — an RDP Wrapper configuration tool;
  • RDPCheck.exe —an RDP check utility (Local RDP Checker);
  • install.bat, uninstall.bat, update.bat — batch files to install, uninstall, and update RDP Wrapper.

To install RDPWrap, run the install.bat file as an administrator. The program will be installed to the C:\Program Files\RDP Wrapper directory.

After the installation is complete, run the RDPConfig.exe. Most likely, immediately after installation, the tool will show that the RDP wrapper is running (Installed, Running, Listening), but not working. Note the red warning [not supported]. It reports that this version of Windows 10 (ver. 10.0.19041.1320) is not supported by the RDPWrapper.

The fact is that for each version of Windows 10 there must be a description in the rdpwrap.ini configuration file. Your config file simply doesn’t have any settings for your Windows 10 build.

The current version of the rdpwrap.ini file can be downloaded here

Manually copy the contents of this page to the “C:\Program Files\RDP Wrapper\rdpwrap.ini” file. Or download the file using the PowerShell cmdlet Invoke-WebRequest (you must first stop the Remote Desktop service):

Stop-Service termservice -Force
Invoke-WebRequest -outfile "C:\Program Files\RDP Wrapper\rdpwrap.ini"
