Termsrv dll windows 10 20h2 patch

To have concurrent user sessions working in Windows 10, you need to make small changes to termsrv.dll file. This file is located in C:\Windows\System32 folder. Before modifying termsrv.dll for the first time, you need to take ownership and assign yourself full permissions. You also need to stop Remote Desktop service (TermService) if it’s running.

DLL files can be modified using any HEX Editor (for example Tiny Hexer). You can do this yourself by replacing strings shown below, or just download patched versions from this page.

Option 2 — RDP Wrapper

Instead of modifying termsrv.dll file you can use RDP Wrapper which acts as a middleman between Terminal Services and Service Control Manager. This way you don’t need to touch termsrv.dll file. Actually, if you already modified your termsrv.dll file, you need to revert to the original version before using this method.

Download and extract RDPWrap-v1.6.1.zip (or newer), then run install.bat as admin. After installation is completed, run RDPConfig.exe. If all items under Diagnostics are green, you should be good to go.

If «Listener state» is » Listening [not supported] «, you will need to update the wrapper’s configuration (.ini) file.

Patched by now: I unistalled the KB4586853 update and after rebooting I went back to version 10.0.19041.84. Then I got [fully supported]. Not a smart solution, but enough by now.

Hallo! Sicher funktioniert es auf Version 10.0.19041.84 (ich habe es auf Ihrem hochgeladenen Bild gesehen), aber (ich weiß nicht warum) meine Version ist 10.0.19041.662 und es funktioniert überhaupt nicht.
Irgendwelche Ideen? Vielen Dank im Voraus.

Inzwischen gepatcht: Ich habe das KB4586853-Update deinstalliert und bin nach dem Neustart zur Version 10.0.19041.84 zurückgekehrt. Dann wurde ich [voll unterstützt]. Keine clevere Lösung, aber mittlerweile genug.

The termsrv.dll file itself is not patched, the INI file works with the normal, in place, termsrv.dll file.

What version of termsrv.dll is shown by RDPConf.exe ?

totwired commented Apr 4, 2021 •

although in 20H2 works, the cursor of the remote machine has continuously the loading circle blinking.
when in vnc or working in the physical machine, this is not a problem.

is there any case that the defender with the rdpwraper service causing this issue?

abhinavdangri commented Dec 11, 2020

Hi Github Community.
Previously I was using RDP Wrapper and it was working correctly.
But after the update in windows 10 I am not able to use the RDP wrapper.
Listener state is listening but not supported.

Please Help me I need this solution ASAP.

go to windows update, and remove the recent windows security updates in the past two days. It will fix it.

arnoldvdm commented Dec 11, 2020 •

For me the same.
I think it’s KB4592438 or the dot net framework: KB4586876

After removing and trying to reinstall:

your device shall not be updated as long as updates are interrupted.
updates will resume on: 19-12-2020

i need the ini file plz

100% that it’s KB4592438

We can ONLY help you and create the ini entries for 10.0.19042 when YOU upload the termsrv.dll for this Windows version!

Upload the termsrv.dll (v.10.0.19042)

watkmogi commented Dec 12, 2020

Morning, mine not working too. Since yesterday.

I have the same termsrv.dll size so I think it’s the same file. (only a higher zip compression (7z))

Mine not working either.
termsrv.zip

asmtron commented Dec 13, 2020 •

@watkmogi

@Huasah
thx for the upload; all the three termsrv.dll’s have the version 10.0.19041.662; and this version is already supported on Win10 10.0.19041.662, 10.0.19041.685.

The autoupdate.bat batch file will automatically update the dpwrap.ini file to support the new termsrv.dll 10.0.19041.662.

Update: 12.12.2020: changing the restart method so we can copy and not stream the new downloaded ini; hope this fixes problems with loading of the new ini file on some systems.

Hi @asmtron, and to those having issues with OS 19042.746.

I recently found this project and encountered the issue about with the listener not being support on OS 19042.746 and I assumed an updated INI file would be needed as I couldn’t find the OS version listed in the ini file from the install.

I was going to upload my termserv.dll when I noticed that the dll file version is 10.0.19041.746 — different from the OS version.

I then found the ini file that @affinityv has created at #999 (comment) which does contain the references for the dll version I have and I followed the instructions in that thread for replacing the ini file with the one affinityv has updated — PROBLEM SOLVED!

Hopefully this is helpful for others now knowing that the OS version and the termserv.dll version can differ (sorry if people already know this but I am new!).

Thanks again to everyone in this community and for the project which has solved a big problem for me.

there a two possible entries for SingleUserOffset [10.0.19041.746].
ver1: SingleUserOffset.x64=0CA4C
ver2: SingleUserOffset.x64=0CB22

on my system Win10 64 Pro only the ver1 entry works. The ver2 entry gives me the [not supported]. Can you please check if ver1 or ver2 works on your win10 ?

Hi asmtron,
in my .ini, I don’t have the version you indicated!
i only have up to version 10.0.17763.1; and even trying «update.bat» doesn’t change anything

edit:
okok, i just «stolen» .ini file from your repo, and it works fine. (ty)
but. can be true? the «official» support discontinued in 2018? 🤔
