How to get multiple remote desktop (RDP) sessions in Windows 10
Posted: 2015-10-13 05:56
The following works with fully patched Windows 10 x64 Enterprise, 2015-10-13. Please bear in mind that sometimes, Windows Update breaks this patch, I will try to keep this up to date, no promises, however.
First, make a copy of the file "termsrv.dll" which is inside "c:windowssystem32", in case you fuck things up.
Go to "Services" and stop "Remote Desktop Services". It cannot be running while you are editing the file.
You must change permission of the file by going to "Properties":"Security" tab, click on "Advanced" and change "Owner" from "TrustedInstaller" to "Administrators". Then hit OK. Now, back in the "Security" tab, mark "Administrators", hit "Edit" and give it "Modify" permission and hit OK.
You can use any hex editor to edit the "termsrv.dll" file.
Find:
Replace that string with:
Now, you can start the "Remote Desktop Services" again.
Personally, I prefer to remove the "Modify" permission from the "Administrators" after I'm done.
There is, of course the RDP Wrapper Library that you can use (never tried it myself) but I don't like to add an extra layer and would like to keep things as clean and original as possible.
Ps. Fuck you Microsoft!
(I would have paid for this function but the motherfuckers won't sell it and I can't use a fucking server operating system in my home!)

I'm just like that myself. That's why I personally use the hex edit solution and alter the .DLL file myself. Much cleaner that way ...and safer! Although, there is the source code available for the RDP Wrapper, I still think altering .DLL file is a much cleaner way to do it. 
I have attached the file in your post so people don't have to go there to download it. You do NOT need to upload files to outside sources in here as long as these are legal files. We allow attachments both for registered and non-registered users.
