How to Allow Multiple RDP Sessions in Windows 10?

Remote users can connect to their Windows 10 computers through the Remote Desktop Services (RDP) running on the Pro and Enterprise editions (but not on Home/Single Language). But there is a restriction on the number of simultaneous RDP sessions – only one remote user can work at a time. If you try to open a second RDP session, a warning appears asking you to disconnect the first user session.

Another user is signed in. If you continue, they’ll be disconnected. Do you want to sign in anyway?

Let’s consider the main restrictions of the Remote Desktop Service usage on Windows 10 (and all previous desktop Windows versions):

RDP access feature supported only in higher Windows editions (Professional and Enterprise). In Windows 10 Home editions, the incoming remote desktop connections are forbidden at all (you can solve this only using the RDP Wrapper Library).
Only one simultaneous RDP connection is supported. When you try to open a second RDP session, the user is prompted to close the existing connection.
If there is a user who works on the console of the computer (locally), then when you try to create a new remote RDP connection, the console session will be terminated. A remote RDP session will be also forcibly terminated if the user will try to log locally.

Actually, the number of simultaneous RDP connections is limited rather by the license (then by any technical aspect). Therefore, this restriction does not allow to create a terminal RDP server based on the workstation that can be used by multiple users. Microsoft’s logic is simple: if you need a Remote Desktop server – buy a Windows Server license, RDS CALs, install and configure the Remote Desktop Session Host (RDSH) role.

From a technical point of view, any Windows version with a sufficient amount of RAM can support simultaneous operation of several dozens of remote users. On average, 150-200 MB of memory is required for one user session, without taking into account the launched apps. Those, the maximum number of simultaneous RDP sessions in theory is limited only by computer resources.

Let’s consider two ways on how to allow simultaneous RDP connections on Windows 10: using the RDP Wrapper application and by editing the termsrv.dll file.

RDP Wrapper: Enable Multiple RDP Sessions on Windows 10
RDP Wrapper not Working on Windows 10
Modifying Termsrv.dll File to Allow Multiple RDP Session

Important. Initially, in the very first version of this post, the main working option that allows you to remove the limit on the number of simultaneous RDP user connections was the way to modify and replace the 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 updated.

As a result, you have to edit this file using Hex editor each time, which is quite tedious. Therefore, you can use the RDP Wrapper Library tool as the main way to deploy a free RDS server on Windows 10.

Note. System modifications described in the article are considered as a violation of Microsoft License Agreement with all the consequences that come with it and you may perform them at your own risk.

RDP Wrapper: Enable Multiple RDP Sessions on Windows 10

The RDP Wrapper Library project allows you to support multiple RDP sessions on Windows 10 without replacing the termsrv.dll file. This software serves 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 enable the support of RDP Host on Windows 10 Home editions. RDP Wrapper does not 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 case of termsrv.dll file update. It allows not to be afraid of Windows updates.

Important. Before installing RDP Wrapper it is important to make sure that you use the original (unpatched) version of the termsrv.dll file. Otherwise, RDP Wrapper may not work stably, or it cannot be started at all.

You can download RDP Wrapper from the GitHub repository: https://github.com/binarymaster/rdpwrap/releases (the latest available version of RDP Wrapper Library – v1.6.2). Based on the information on the developer page, all versions of Windows are supported. Windows 10 is supported up to the 1809 build (although , everything also works fine in Windows 110 1909, see the solution below).

The RDPWrap-v1.6.2.zip archive contains some files:

RDPWinst.exe — an RDP Wrapper Library install/uninstall program;
RDPConf.exe — an RDP Wrapper configuration utility;
RDPCheck.exe — Local RDP Checker — an RDP check utility;
install.bat, uninstall.bat, update.bat — batch files for installation, uninstallation and update of RDP Wrapper.

To install the RDPWrap, run the 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 Files\RDP Wrapper directory.

When the installation is over, run the RDPConfig.exe. Make sure that all elements on the Diagnostics section are green.

Run the RDPCheck.exe and try to open a second RDP session (or connect several RDP sessions from remote computers). It worked out well! Now your Windows 10 allows two (and more) users to use different RDP sessions simultaneously.

The RDPWrap utility supports all Windows editions: Windows 7, Windows 8.1, and Windows 10. Thus, you can build your own terminal (RDS) server on any desktop instance of Windows.

Also interesting features of the RDP Wrapper are:

The option Hide users on logon screen allows you to hide the list of users from the Windows Logon Screen;
If you disable the Single session per user option, multiple simultaneous RDP sessions will be allowed under the same user account (the registry parameter fSingleSessionPerUser = 0 is set under the key HKLM\SYSTEM\ CurrentControlSet\Control\Terminal Server\fSingleSessionPerUser);
RDP Port — you can change the Remote Desktop port number from 3389 to any other;
In the Session Shadowing Mode section you can change the remote control (shadow) connection permissions to the Windows 10 RDP sessions.

RDP Wrapper not Working on Windows 10

Let’s consider what to do if you cannot use several RDP connections in Windows 10 even with the installed RDP Wrapper tool.

In my case, since there is no direct Internet access on the computer, the RDPWrap could not get the new version of the rdpwrap.ini file from GitHub with the settings for the latest Windows versions. Therefore, the RDConfig utility showed the status [not supported].

Download the rdpwrap.ini file from the developer’s page and place it in the installation folder (C:\Program Files\RDP Wrapper\rdpwrap.ini). Restart the TermService and make sure that the state [not supported] is changed to [fully supported].

If the RDP Wrapper utility doesn’t work properly after updating the rdpwrap.ini file, the problem can occur because of a new build of Windows 10 you are using. Try to download the new rdpwrap.ini for your Windows 10 version build from here https://github.com/fre4kyC0de/rdpwrap.

You can get the rdpwrap.ini for the Windows 10 1909 10.0.18363.476 with the following link rdpwrap_10.0.18363.476_1909.zip.

Also, if you have problems with RDPWrap, you can open the issue at https://github.com/stascorp/rdpwrap/issues. Here you can find the actual rdpwrap.ini file before updating it in the official repository.

To replace the rdpwrap.ini file:

Stop the termservice: get-service termservice | stop-service
Replace the rdpwrap.ini file in the directory C:\Program Files\RDP Wrapper\;
Restart your computer;
Run the RDPConf.exe and make sure all statuses turn green.

If after installing security updates or upgrading the Windows 10 build, RDP Wrapper does not work correctly, check if the “Listener state: Not listening” is displayed in the Diagnostics section.

Try to update the C:\Program Files\RDP Wrapper\rdpwrap.ini file using the update.bat script (or manually) and reinstall the service:

rdpwinst.exe -u rdpwinst.exe -i

It happens that when you try to establish a second RDP connection under a different user account, you see a warning:

The number of connections to this computer is limited and all connections are in use right now. Try connecting later or contact your system administrator.

In this case, you can use the Local Group Policy Editor (gpedit.msc) to enable the policy “Limit number of connections” under Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Connections section. Change its value to 999999.

Restart your computer to apply new policy settings.

Modifying Termsrv.dll File to Allow Multiple RDP Session

To remove the restriction on the number of concurrent RDP user connections in Windows 10 without using rdpwraper, you can replace the original termsrv.dll file. This is the library file used by the Remote Desktop Service. The file is located in C:\Windows\System32 directory.

Before you edit or replace the termsrv.dll file, it is advisable to create its backup copy. If necessary, this will help you to return to the original file version:

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

Before you edit the termsrv.dll file, you have to become its owner and give the Administrators group the full permissions to it. The easiest way to do this is from the command prompt. To change the file owner from TrustedInstaller to a local administrators group use the command:

takeown /F c:\Windows\System32\termsrv.dll /A

SUCCESS: The file (or folder): c:\Windows\System32\termsrv.dll now owned by the administrators group

Now grant the local administrators group Full Control permission on the termsrv.dll file:

icacls c:\Windows\System32\termsrv.dll /grant Administrators:F

processed file: c:\Windows\System32\termsrv.dll Successfully processed 1 files; Failed processing 0 files.

After that, stop the Remote Desktop service (TermService) from the services.msc console or from the command prompt:

Net stop TermService

Before moving on, you need to get your version (build number) of Windows 10. Open the PowerShell console and run the command:

Get-ComputerInfo | select WindowsProductName, WindowsVersion

I have Windows 10 build 1909 installed on my computer.

Then open the termsrv.dll file using any HEX editor (for example, Tiny Hexer). Depending on your Windows 10 build, you need to find and replace the code according to the table below:

Windows 10 build	Find the string	Replace with
Windows 10 x64 1909	39 81 3C 06 00 00 0F 84 5D 61 01 00	B8 00 01 00 00 89 81 38 06 00 00 90
Windows 10 x64 1903	39 81 3C 06 00 00 0F 84 5D 61 01 00
Windows 10 x64 1809	39 81 3C 06 00 00 0F 84 3B 2B 01 00
Windows 10 x64 1803	8B 99 3C 06 00 00 8B B9 38 06 00 00
Windows 10 x64 1709	39 81 3C 06 00 00 0F 84 B1 7D 02 00

For example, for Windows 10 x64 RTM (10240) with the termsrv.dll file version 10.0.10240.16384, you need to find the line:

39 81 3C 06 00 00 0F 84 73 42 02 00

and replace it with:

B8 00 01 00 00 89 81 38 06 00 00 90

Save the file and run the TermService.

Already patched termsrv.dll file for Windows 10 Pro x64 can be downloaded here: termsrv_for_windows_10_x64_10240.zip

If something went wrong and you experience some problems with the Remote Desktop service, stop the service and replace the modified termsrv.dll file with the original version:

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

The advantage of the method of enabling multiple RDP sessions in Windows 10 by replacing the termsrv.dll file is that antiviruses do not respond on it (unlike the RDPWrap, which is detected by many antiviruses as a Malware/HackTool/Trojan).

The main drawback is that you will have to manually edit the termsrv.dll file each time you upgrade the Windows 10 build (or when updating the version of the termsrv.dll file during the installation of monthly cumulative updates).

This isnt working

The listening state is not working

Ben February 10, 2016 - 8:51 pm

Run the update.bat with administrator privileges

aditi February 29, 2016 - 5:09 am

Hi Ben
I tried after update.bat file and still its not supporting for Listening.

Oleksiy Shtanko March 12, 2016 - 12:27 pm

On GitHub there is no archive with .exe’s anymore, only source code. Anyone have the already compiled version?

glenn March 12, 2016 - 3:20 pm

I cant find it either any help would be appreciate email to gdp4145@hotmail.com

Oleksiy Shtanko March 12, 2016 - 4:33 pm

Apparently, the link in the article leads to an old or somewhat different fork of the project which contains only source codes.
The .exe’s are in the Release section over here: https://github.com/stascorp/rdpwrap/releases

Meher March 17, 2016 - 6:02 am

Hi I am also getting same problem like Listener state [not supported ] and I have ran the update.bat file then I am getting error as Failed to Download latest INI from GitHub.

Jesus March 17, 2016 - 4:39 pm

A mi me ha funcionado correctamente tras ejecutar el archivo .bat. Comprabado en un Windows 10 Pro 64bits

Jesus March 17, 2016 - 4:40 pm

Perdón me refería al ejecutar el ACTUALIZADOR.BAT

Dave March 17, 2016 - 6:32 pm

Thanks. The link to rdpwrap is stale and it’s confusing because there are downloads available but none of them contain binaries. The link should be https://github.com/stascorp/rdpwrap/releases.

MichaelZ March 24, 2016 - 4:04 am

I’m running Windows 10 Home and installed RDP Wrapper from the following binary listed above: “https://github.com/stascorp/rdpwrap/releases”
A fix for the listener state when running RDPConf.exe or if you get a error in Update.bat about a serive not starting is to enable “Routing and Remote Access” in services.
Change it from disabled to automatic, then right click the service and start it. This worked for me I hope it helps.

ArtS March 28, 2016 - 11:25 pm

I found a site with the zip file containing the wininst.exe file.
https://github.com/stascorp/rdpwrap/releases
I installed RDP Wrap and ran the Config. Everything was Green.
However, when I try to run a second user remotely, it removes the first user.
Everything looks good. On the host pc I am allowing all connections.
Any help would be appreciated.

Hello,
If a User is connected through RDP to Windows 10 via USER1, How to prevent other users from other PCs to connect remotely to the same PC with Widows 10 using USER1.
In Other Words if there is a live RDP connection, I want to prevent other users to connect remotely at the same time forcing the live connection to break?

admin April 4, 2016 - 9:43 am

Hi
You can’t prevent such behavior.
Perhaps it will be easier to create a separate account for each remote user or allow multiple Remote Desktop sessions per user (registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer-> fSingleSessionPerUser = 0 )

larrybud December 16, 2020 - 4:56 pm

You would prevent them from doing so with a password.

If you only want a connection from a specific computer, set up firewall rules for port 3389 to only allow a certain mac address in

Max Korman April 4, 2016 - 9:11 am

By default each user is restricted to a single Remote Desktop session. You can allow multiple Remote Desktop sessions per user by changing a registry key:
Create (or edit) the follwoing registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer
Create a new DWORD value with name fSingleSessionPerUser
The possible values for this setting :
0×0 Allow multiple sessions per user
0×1 Force each user to a single session

Dennis May 25, 2016 - 1:28 pm

fSingleSessionPerUser only works for Windows Server versions.

Daniel June 11, 2016 - 12:08 pm

Not interested in only two, how about 10 or so?

Werner Lieske July 26, 2016 - 12:48 pm

Did you ever find out if this is possible? I have a client that wants to do this for about 20 users.

After installing latest updates on Windows, RDP Wrapper Library has stopped normal functioning
To fix this issue, try to run update.bat from release package

Hans September 29, 2016 - 11:43 am

Hi. Is is possible, that RDP Wrapper still does not work?

admin September 30, 2016 - 5:08 am

Hi,

You have tried to update using a update.bat file?

Hans October 2, 2016 - 8:16 pm

Hi, yes I have. After deinstalling and installing again the first log-in works sometimes, but then RDP only says “connecting…” for a few seconds and just stops without doing anything. The problem started after Windows 10 updated to 1607 (Build 14393.xxx) a couple of days ago.

Max October 3, 2016 - 7:43 am

Try to install RDP Wrapper Library v1.6.1 (_https://github.com/stascorp/rdpwrap/releases). According to the developers, support of Windovs 10.0.14931.1000 and 10.0.14936.1000 was added to the ini file (_https://github.com/stascorp/rdpwrap/issues/168)

Hans October 5, 2016 - 11:19 am

Hi, thanks for the replay. Sadly I am using 1.6.1, it is not working. Only optionI found so far is uninstalling, setting windows settings back to allowing RDP (after every uninstall it is set to no) and reinstalling. Then I have about 30 seconds to one minute to log every external user into windows.
I will try uninstalling the windows update, maybe that will help until windows forces the update back in.

Hans October 7, 2016 - 2:28 pm

I am back to 1511, that works without a problem.

Eduardo October 26, 2016 - 12:32 am

Thanks . It is working . I use RDP Wrapper library

Jason January 15, 2017 - 11:33 pm

Thanks for this article! Works perfectly. This, in combination with Hamachi (paid version so the service stays alive after logout), is a great!

Daniel Potter February 23, 2017 - 10:02 am

what is the maximum number of concurrent logged in users that it will support?

Simon March 14, 2017 - 8:39 pm

Is it possible to have 1 local user (physically at the PC) and 1 remote simultaneously)? I’m on Windows 10 Pro.

Christian July 19, 2017 - 5:04 am

Is it possible to use a computer with rdpwrapper local and with one or two remote connections?

How to configure?

If I am logged-in locally on my computer and work and a remote connection tries to get in then my local account must be closed otherwise the remote connecrion can be placed.
Is that normal??
Can I not use the computer local and remote (with another user account? – of course) at the same time?

It stop working after last update 1803 🙁

javier May 3, 2018 - 7:22 am

I will answer myself, if you overwrite termsrv.dll from older version 10.0.16299.15 for example you will be able to install correctly and works correctly with last version 1803

I cant do the hex editing, because the hex editor is not willing to open the dll. I did the ownership change on the dll, I gave full access to it, but still no luck. I used RDP Wrapper earlier, but it doesnt support build 17134. Can somebody upload please the updated ini for RDP wrapper OR the patched dll (for build 17134)?

Serg May 11, 2018 - 7:41 am

Replace the file in the :\Windows\system32\termsrv.dll directory with the old version of C:\Windows.old\system32\termsrv.dll, and restart the computer. After that, rdp wrapper starts working again! Tested on Windows 10 1803 Spring Update!

John C McKenney June 2, 2018 - 2:14 pm

Avira says this is malware. Chrome says it’s dangerous. Comments about that?

Garry May 6, 2019 - 4:06 pm

Microsoft has the power to have any software that mods Windows listed as “malware” to scare people away from using it.

Greg August 21, 2018 - 12:31 pm

My current version of termsrv.dll is 17741 and my prior version is 17738. I notice that the size of termsrv has changed dramatically from 339k to 992k. Both of these releases also control an additional service called Remote Desktop Services UserMode Port Redirector, I don’t know if the older versions controlled that service or not. Bottom line, I can’t modify termsrv because the hex string to search for is no longer in the module, rdpwrapper does not work with the updated termsrv. I downloaded the patched version of termsrv.dll but haven’t tried using it yet. that will be my next adventure. Somehow I think it may not work only because it appears the code has been redesigned to function differently than was originally designed. However, I’m going to give it a try.

Greg August 21, 2018 - 1:13 pm

Tried the downloaded version of termsrv, it just crashed when starting. put 17741 back in place. Anyone have any ideas here?

Ross February 8, 2019 - 8:38 pm

Very funny, It looks like no one is using antivirus here…
The file RDPConf.exe contains a virus that gives access to external people to your PC (RemAdmin)

Gechurch July 15, 2019 - 4:29 am

The point of the software is to modify Windows to allow multiple remote connections. It’s expected behaviour to have antivirus software flag it as a risk that allows remote connections.

gming February 13, 2019 - 5:07 am

I also installed
17763.107.101029-1455.rs5_release_svc_refresh_CLIENTENTERPRISEEVAL_OEMRET_x64FRE_en-us
4518890KB
windows enterprise 1809 evaluation 90 days & applied patch. It was working perfectly.
It was working as single user with many multisession at a time, (multi login single user RDP as it is normal with windows server 2016/2008)
It was also working as different terminal services users with multisession to a single machine.
I see there updates on machine were installed and then single user with multiple session is no longer working. I don’t cause the issue. Update KB4487044 / KB4470755 / KB4483452 installed on 13-Feb-2019.
Later i uninstalled those two KB but still the multi login/ simultaneously single user with terminal services for different sessions didn’t worked. (the kb4470788 was not removable)
I used two things to make it happened

On Win 10 Pro i had to set via gpeditor
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.

From here, first set the Restrict Remote Desktop Services user to a single Remote Desktop Services session parameter to Disabled.

Next, double-click on Limit number of connections and then set the RD Maximum Connections allowed to 999999.

Ver 1.5.0.0 service ver. 10.0.17763.292 is showing not supported no matter what I try. This will not allow multiple people to use the machine. I continue to get “another user is signed in if you continue, they’ll be disconnected do you want to sign in anyway”.
What am I missing here? The updated .ini is there. Everything appears to be correct but it will not work.

Sean C March 28, 2019 - 6:48 am

Use an updated INI file that supports 1809 and it will work as expected… read the thread here for details:
https://github.com/stascorp/rdpwrap/issues/699

Suddenly a restrictionon 2 rdp sessions appeared in Windows 7.
When reinstalling rdpwrapper:
[!] This version of Terminal Services is supported partially.
It means you may have some limitations such as only 2 concurrent sessions.
Try running “update.bat” or “RDPWInst -w” to download latest INI file.
If it doesn’t help, send your termsrv.dll to project developer for support.
After removing KB4489878 everything is OK.

dk April 12, 2019 - 5:29 am

The rdpwrapper stopped working in my Windows 10.0.17134.706 (windows 10 1803 x 64) after installing new updates on April 11, 2019.
I upgraded my Windows 10 to 1809 (the file was updated to 10.0.17763.437), then I edited the rdpwrap.ini file and add the following section:
[10.0.17763.437-SLInit]
bInitialized.x86 =CD798
bServerSku.x86 =CD79C
lMaxUserSessions.x86 =CD7A0

Johnny May 22, 2019 - 9:40 pm

Hey,

I got the latest rdpwrap.ini:
https://github.com/stascorp/rdpwrap/files/3062713/rdpwrap.zip

to replace the existing one, I had to first stop the Remote Desktop Services windows service.
(which will also stop another service: Remote Desktop Services UserMode Port Redirector)

The file is now editable/replaceable.
Then replace C:\Program Files\RDP Wrapper\rdpwrap.ini (in my case I just copy paste the extra section but I needed to run my text editor in Administrator privilege mode)
restart the 2 windows service (also make sure they are in automatic start mode)

And bingo, I now see [fully supported]

Aruna Telshan June 28, 2019 - 6:56 am

Wow! Its working.. Thanks for the info i have been searched a solution for hours.

Just tested on Windows 10 x64 1809. I chose to restart the PC tho. Concurrent Remote Desktop sessions is functional.

What I did: installed RDPWrap 2.6.2.
That’s all.

Rohan Nish June 18, 2019 - 8:21 am

RDPWRAPPER works fine for me on 1809 but I noticed that the printer redirection has stopped working, anyone else have this problem

Johnix June 27, 2019 - 12:02 am

Hi. Is the Wrapper use illegal?

Remote access. No more than once every 90 days, you may designate a single user who physically uses the licensed device as the licensed user. The licensed user may access the licensed device from another device using remote access technologies. Other users, at different times, may access the licensed device from another device using remote access technologies, but only on devices separately licensed to run the same or higher edition of this software.

Yes, this is violation of the Microsoft licensing agreement.

By mistake I click on rdpcheck file and now my system not login after the restart.
It showing username and password and after putting the credentials, login error.

admin July 8, 2019 - 4:40 am

I think you need to reset the local administrator password using a boot, rescue or install disk.

Ion July 24, 2019 - 7:21 pm

Hello,
we did a security update on windows 10 Pro, today 7/24/19, and after it we can connect only one RDP at a time. So we changed the termsrv.dll, did all as instructed, and now we can’t connect even one RDP, we get Access Denied error. Any suggestions how we may solve this?

Ion July 24, 2019 - 7:23 pm

also worth to note that I disconnected the windows auto-updater, and for some reason it still told one of the users (administrators) that there is an update that has to be made.

Sam September 18, 2019 - 10:25 pm

Cannot get concurrent session to work on Win 10 Pro version 1903 OS build 18362.356. All green in RDPConf, except still shows “not supported”. Followed all possible instructions in correct order including replacing INI file and restarting appropriate services and/or restarting computer – nothing works. All was good 1 week ago. Any ideas? Will appreciate any suggestions, impacting my work big time.

Rob September 21, 2019 - 8:54 pm

If you updated to version 1903 less than 10 days ago you can go to settins > updates > recovery and use the go back to the previous version of Windows 10 option. Version 1903 was recently released and not sure if there is a fix for it yet.

Hi there, it worked for me aswell (after a few hours digging).
1903 Win 10 Pro with Rob’s solution. (Thanks Rob from Robb)
I previously installed RDP Wrapper and got all green but didn’t work till I did the termsvr.dll change, so I’m not sure what is really doing the trick LOL.

Brau0591 January 30, 2020 - 4:33 pm

Hi, I’m having one issue with this, one remote connection get suddenly close and I have to connect again, it doesn’t show me any error or something, it just close the session, any idea why this Is happening?

ROBB January 31, 2020 - 7:55 am

Hi there, maybe somebody has logged in. Have you checked that more than one session are allowed?

eyallvy February 1, 2020 - 5:52 pm

Great and detailed instructions, obviously written by a real pro. However…

1. The RDP Wrapper software gets marked as malware, both by Malwarebytes and Trend Micro antivirus apps. In comes up relatively clean on the VirusTotal site, but I didn’t dare ignore my antivirus app warnings and opted instead for editing the termsvr.dll file as per instructions. The result works fine, but the instructions about editing it appear to be missing a small but crucial item…

2. The Tiny Hexer editor app refused to edit termsvr.dll while in was inside the system32 folder and gave an error message. I intuitively copied it out to another, non-system folder and the edit went fine. I then copied the edited file back into the system32 folder and all was well.

Please keep up the great work and add updates as regards the edits required to termsvr.dll in future updates of W10.

n19htmare February 10, 2020 - 5:00 pm

Yep a few people are saying RDP Wrapper is infected. Is there any other software?

admin February 11, 2020 - 7:26 am

You can use the modified termsrv.dll file instead of RDP Wrapper.

BobH February 15, 2020 - 3:59 pm

Still get ‘listener not supported’ on Windows 10 Home v1909 with RDP Wrapper v1.6.2, latest version of rdpwrap.ini and patching termsrv.dll as described by Rob and the hex editing table you had provided. I also tried enabling Routing and Remote Access in services. I had run update.bat and even tried the RDPWinst commands with no success. I guess there’s no way to get RDP to work with Windows 10 Home.

Robert February 17, 2020 - 3:59 am

With Windows 10 x64 1909, the listening state is no supported, even with the latest ini file

Jim March 6, 2020 - 8:54 pm

Hei is there somewhere info about rdp patch 20h1 (19041) insider? The patchted rdp file from 1903 do not work.

Someone April 4, 2020 - 9:50 am

It worked for me by modified termsrv.dll. Thank you.

Dean April 20, 2020 - 4:24 pm

Hi,
So I think I’d like to use the code modification method – changing the termsrv.dll file – and Not use RDP Wrapper. It sounds straightforward. I don’t want to install software that might set off virus warning bells. And all I really care about is being able to allow a 2nd user (RDP or local) without bumping an existing user (RDP or local) off.

However, it seems RDP Wrapper tool provides for numerous parameters:
– specifying a different RDP port
– type of Authentication Mode
– type of Session Shadowing Mode
– etc.

Does anybody know What the termsrv.dll code changes above actually does ?
What settings/configuration is being setup ?
For instance, I specifically do Not want to use the default port (3389). But does the termsrv.dll code changes above allow for a port other than 3389 ?

Thanks, appreciate any helpful responses/comments.

Dean April 20, 2020 - 4:26 pm

fyi – I already have my RDP setup with a different port #

admin April 21, 2020 - 6:26 am

You can change the RDP listening port number on your computer in accordance with the article http://woshub.com/change-rdp-port-3389-windows/

Dean April 24, 2020 - 7:12 pm

Thanks for the response, but I already have my RDP connection setup with a different port #. The gist of my question is, what does the code change method actually do ?? For example, one of my concerns is, if I change the termsrv.dll file…. does that code (those parameters) override my port # setup…. and ‘that’ code relies on using the default of 3389 ? How about Authentication Mode or Session Shadowing Mode, etc.

Bharath TSR May 1, 2020 - 11:43 am

Hi
I tried using RDP wraper but I could not fix the error not supported.
Then I tried editing termsrv.dll and it worked great. Thank you So much

NOT ALL 1909 versions are the same. My build is: Version 10.0.18363.836

I also edited the INI file in Program Files\RDP Wrapper to include that version at the end. Just copied the latest 10.0.1836* version groups and added the current version.

PCFixerGuy June 18, 2020 - 10:21 am

Just a heads up everyone: In THIS instance, RDPCheck.exe still told me “Not Supported” but it DOES work.

HI. need the rdp edit for window 10 version 2004 which they keep updating.
i edited termsrv.dll and rebooted .. service started ok.. but no mulitiple logins.
so msn has done some thing else or the hex edis for version 1909 does not work on 2004.
i have not tried rdp wrapper becuse it wont down load under virus protection. i may
turn that off and down load.

Everyone, Thanks to the great work by the author and everyone who has posted to assist everyone. I have the new version 2004 and have used tiny Hexer, just as the author says and got everything working fine. Here is the needed data for the new version and how I found the area to make the change. Using Tiny Hexor I used a backup to mod first (follow the directions on ownership and icals and making backup) Use tiny hexer to find
Windows 10 x64 2004 39 81 3C 06 00 00 0F 84 D9 51 01 00
Replace with B8 00 01 00 00 89 81 38 06 00 00 90
In the future search for just 39 81 3C 06 00 00 as that never appears to change and replace the full hex (12 pairs starting with 39 81 3C 06 00 00 ) and replace with B8 00 01 00 00 89 81 38 06 00 00 90
Hopes this helps everyone and stay safe and healthy.

When I do a find for the value it states “No Results”. Even if i just search for 39, I get the same results so I know I am doing something wrong. I am not very familiar with Hex Editing software. Can anyone provide more details in how to change the termsvr.dll file with TinyHexer? I have tried using RDP Wrapper and although everything appears as if it should work, I cannot get multiple RDP sessions to work. By the way, EXCELLENTLY written by the Author and great feedback as well!!

Just found windows build 2004 on my machine after auto update. Not finding the code strings in the termsrv.dll anymore. Has the hex editing instruction here no longer effective with this latest build?

Same here! Las windows update has modified termsrv.dll and can’t find the string anymore.
Someone can tell what is the new string to search for ?

Thanks.

Microsoft Windows [Version 10.0.19041.746]
For this version what code should be looked up for and replaced with.

Microsoft has been updated very quick recently.
Computer has just updated to latest version windows 10 pro version 2004, OS 19041.264

recheck termsrv.dll
It has been overwrote by the latest update.

It is
39 81 3c 06 00 00 0F 84 D9 51 01 00

Replace to
B8 00 01 00 00 89 81 38 06 00 00 90

This solution runs without additional software RDP Wrapper or RD Plus.
It is successful allowed multiple users access at same time simultaneously。

Used this on 20H2 build 19041.746

searched for
39 81 3C 06 00 00 0F 84 01 5E 01 00
replaced with
B8 00 01 00 00 89 81 38 06 00 00 90

Works without RDPWrapper .. of course backup termsrv.dll before editing.

Hmmm, for me didn’t work – Win 10 Pro ver. 2004 – fileversion 10.0.19041.746 – TermService wont start… Any suggestions? Thank You very much.

Jozef February 2, 2021 - 10:52 am

Seconadry it worked ;o)

BobH January 24, 2021 - 6:42 am

Thanks Kalandor – that worked for 20H2! FYI – can’t use Tiny Hexer to patch termsrv.dll in \windows\system32, even after taking ownership and setting full access (it would never find the file, probably due to inherited permissions). Had to copy termsrv.dll to another directory (i.e Downloads), use Tiny Hexer to patch that file, then copy the file back to \windows\system32

Worked for me. However, is there a sustainable way to update this string in sebsequent versions? I have 19042.844 today. Thanks

Manny February 5, 2021 - 1:16 am

So, Windows just updated this again.
The version of the new termsrv.dll is 10.0.19041.789
I can’t find the above sequence in the file.
Anyone that could shine a light on this would be great!
Thanks you!

Manny February 5, 2021 - 1:46 pm

Never mind that, it’s the same string as .746. I have looked at it and at first I wasn’t finding that string. I was probably doing something wrong in the search. Tried again after a good night of sleep and, well, it’s working now. Tested!
