Multiple RDP [Remote Desktop] sessions in Windows 10
Option 1 - Modifyingtermsrv.dll
To have concurrent usersessions working in Windows 10, you need to make small changes to termsrv.dllfile. This file is locatedinC:\Windows\System32 folder.Before modifying termsrv.dllfor the first time, you need to take ownership and assign yourself full permissions. You also need to stopRemote Desktopservice [TermService] if it's running.
DLL files can be modified using any HEX Editor [for exampleTiny Hexer]. You can do this yourself by replacing the strings shown below, or just download patched versions from this page.

Option 2 - RDP Wrapper
Instead of modifyingtermsrv.dllfile you can useRDP Wrapperwhichacts as a middleman between Terminal Services andService Control Manager. This way you don't need to touch termsrv.dllfile. Actually, if you already modified yourtermsrv.dllfile, you need to revert to the original version before using this method.
Download and extractRDPWrap-v1.6.1.zip [or newer], then runinstall.bat as admin.After installation is completed, runRDPConfig.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.
With the latest version of RDP Wrapper you no longer need to updaterdpwrap.inimanually. Simply run update.batand everything will be done automatically.
Ifupdate.batdoesn't add support to your Windows version, try checking Open Issues on RDP Wrapper GitHub page. You may find how to manually updaterdpwrap.ini until official support is added.

Comments
I just recently gave this a shot with Windows 10 Consumer Preview Build 10532. I can't seem to get it to work with this build. Any help would be greatly appreciated. I think it is because of the version of the termsrv.dll I have included a link to the dll.

Enjoy!

P.S. Please someone to reupload because of download limits on free file sharing servers!
I've searched the net but could not find similar issues to mine. Win8.1 Pro was upgraded to Win10 Pro Final. I have this weird issue where port 3389 is not listening by checking "netstat -na|findstr 3389". The port is by default set to 3389 in the registry. The service is running normally by checking both services and "sc query termservice". There's nothing about RDP errors in the event logs. Though not related, I've also added RDP to the firewall just in case. All troubleshooting was done with either RDP service restart or reboot.
I've also tried using RDP Wrapper, the status is all green except "Listener state: Not listening" in red [it does shows [fully supported]]. Do you have any idea? I've attached the screenshot. Thanks.

in termsrv.dll search for:

replace by:
B8 00 01 00 00 89 81 38 06 00 00 90
As usual, to modify system dlls, take ownership, set full permission. Don't forget to stop Remote Desktop Services in service console.

For me, it's working well on Win10 Pro x64 [Upgrade from Win7 Pro x64]. Used the instructions in the youtube video and updated the .ini manually. Everything's working well!

Had to put the old termsrv back into play to get it to start...bummer :[The Remote Desktop Services service terminated with the following error:

Works on 10240 - could cause some sound issues.
4. Go to c:\windows\syst em32 and copy the file "termsrv.dll" to some folder [if something goes wrong].
5. Copy the termsrv.dll that you downloaded from this website to the original c:\windows\syst em32 [overwrite the current file].
2. Run "services.msc", find "Remote Desktop Services", right click and click "stop".
If it hangs [which happens often], open cmd and type: "sc queryex termservice". It will print some crap, just find the value next to "PID" [process id].
Next just force killing the process, by typing "taskkill.exe /pid:123 /f" [assuming 123 is the PID your found earlier].
