How to get multiple remote desktop (RDP) sessions in Windows 10

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. :roll:

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:

Code: Select all

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

Replace that string with:

Code: Select all

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

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 try my best to avoid 3rd party software, if I can get away with using the Microsoft basics, I'm fine with that.

Ah yeah, 100% agreed! :clap: 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. :mrgreen:

@z3r0ne,

Oh dear God, that was a total obnoxious link that you used to upload your file. :lol: 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.

Anyway, thank you for the file. Although, I personally prefer to "create / make / alter" on my own, especially when it comes to system files which allow outside internet connection :roll: ...but I guess someone will have a use from your file as well if they don't like to use a hex edit tool.

Ps. I have sent an email to you, please make sure to reply to it, otherwise, your account will be deleted. Please bear in mind that your posts will not get deleted and non-registered users can use our services as well. We just don't like "dead" member accounts we can't reach. :mrgreen:

Last but not least, welcome! :grin:

I need a patch for WinXp Pro. I know the offset is different but maybe you can help me.

Which version is it? I mean, 32bit or 64bit? Also, if you have any build number, it would help. Hm, is it SP2 or SP3?

Winxp sp3 32bit termsrv.dll 5.1.2600.5815, there are patches online but they didn't work.
