Termsrv.dll, File description: Remote Desktop Session Host Server Remote Connections Manager. Errors related to termsrv.dll can arise for a few different different reasons. For instance, a faulty application, termsrv.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry. There is many use cases when you need to enable concurrent remote sessions for a Windows system. When working for an organization and using W2008 (R2), W2012 (R2) servers as file systems, DCs, and where you work with several admins in a team, this setting is handy. For the client systems (XP, Vista, Windows 7, Windows 8), that’s another story.

Like in previous client versions of Microsoft operation systems, users of Windows 10 Pro and Enterprise (but not Home) editions can connect their computers remotely using Remote Desktop Connection (RDP) service. However, there is a restriction on the number of simultaneous RDP sessions: only one remote user can work at a time. When you try to open a second RDP session, the session of the first user is prompted to be closed.
Another user is signed in. If you continue, they’ll be disconnected. Do you want to sign in anyway?
The fact is that the desktop editions of Microsoft operating systems have the following basic limitations when using the Remote Desktop service:
Actually, the number of simultaneous RDP connections is limited rather by the license, which does not allow to create an RDP server based on the workstation for use by multiple users, than by any technical aspect. From a technical point of view, any Windows version, if there is enough memory, can support simultaneous operation of several dozens of remote users if there is enough memory (on average, 150-200 MB of memory is required for one session, without taking into account the launched apps). Those the maximum number of simultaneous RDP sessions in theory is limited only by computer resources.
Tip. In Windows 10 Home editions, the incoming remote desktop connections are forbidden at all. The problem, however, can be solved using RDP Wrapper Library.
Let’s consider two ways on how to eliminate the restriction of simultaneous RDP connections to Windows 10:
Important. Initially, in the very first version of this article, the main working option that allows you to remove the limit on the number of simultaneous RDP connections was the way to modify and replace termsrv.dll file in the %SystemRoot%System32 folder. However, when you install a new Windows 10 build or some security updates, this file can be replaced. As a result, you have to edit this file using Hex editor each time, which is quite tedious. Therefore, as the main way to organize a free terminal server on Windows 10 is to use the RDP Wrapper Library utility.
Note. System modifications described in the article will be probably treated as a violation of Microsoft License Agreement with all the consequences that come with it.
RDP Wrapper Library
The alternative to termsrv.dll file modification is to use RDP Wrapper Library project. This software serves as a layer between SCM (Service Control Manager) and Terminal Services and allows not only to enable the support of several simultaneous RDP sessions, but also to enable the support of RDP Host on Windows 10 Home editions. RDP Wrapper does not make any changes to termsrv.dll file, it just loads termsrv library with the changed parameters.
Thus, this solution will work even in case of termsrv.dll file update. It allows not to be afraid of Windows updates.
Important. Before installing RDP Wrapper: it is important to use the original (unpatched) version of the termsrv.dll file. Otherwise, RDP Wrapper may not work stably, or it cannot be started at all.
RDP Wrapper can be downloaded from GitHub repository: https://github.com/binarymaster/rdpwrap/releases the latest available version of RDP Wrapper Library v1.6.2 was released relatively recently – December 28, 2017). Based on the information on the developer page, all versions of Windows are supported. Windows 10 is supported right up to the version of Insider Preview build 10.0.17063.1000 (from December 13, 2017).
Tip. By the way, RDP Wrapper Library source code is also available. It means that if required, you can compile executables by yourself.
RDPWrap-v1.6.2.zip archive contains some files:
To install the utility, run install.bat with the Administrator privileges. During the installation process, the utility accessing the GitHub site for the latest version of the ini file. To undo this, remove the -o flag in the install.bat file. The program will be installed in the C:Program FilesRDP Wrapper directory.
When the installation is over, run RDPConfig.exe. Make sure that all elements in Diagnostics section are green.
Note. In my case, since there is no Internet access on the computer, the program could not get the current version of the INI file settings from Github for my Windows edition. Therefore, the status is [not supported]. Download the rdpwrap.ini file from the development page and place it in the installation folder. Restart the service and make sure that [not supported] is changed to [fully supported].
Several interesting features of the new version of RDP Wrapper:
In the event that after updating the Windows version, RDP Wrapper does not work, check that the Listener state: Not listening is listed in the Diagnostics section.
Try to update the ini file using the update.bat script (or manually) and reinstall the service:
rdpwinst.exe -u
Try to open the second RDP session (make sure that RDP access is enabled in the system settings). It worked out well! Now, our Windows 10 allows two users to start RDP sessions simultaneously.
Terminal Server On Windows 10The Modification of termsrv.dll
Note. This method is applicable only to the RTM version of Windows 10 x64 (10240).
The restriction on the number of RDP connections can be eliminated using termsrv.dll file (a library file used by Remote Desktop Services) modification. The file is located in C:WindowsSystem32) directory.

Before termsrv.dll file modification, create its backup (if necessary, you can use the original version of the file):
copy c:WindowsSystem32termsrv.dll termsrv.dll_backup
Before termsrv.dll file editing, you have to become its owner and give the Administrators group the full rights to it (all steps are similar to those that described in the article “Enable Multiple Concurrent RDP Sessions in Windows 8”). After that, stop Remote Desktop service (TermService) in services.msc console or from the command prompt:
Net stop TermService
For Windows 10 x64 RTM edition (termsrv.dll file version is 10.0.10240.16384):
Open termsrv.dll file using any HEX editor (for example, Tiny Hexer)
Find the line:

Replace it with:
B8 00 01 00 00 89 81 38 06 00 00 90
