Hacking Windows 7 Media Center

Enable Concurrent User Sessions in Windows 7

by @ 8:30 am on February 1st, 2009 in programs, windows 7 with 27 Comments

Nothing kills a Media Center user like having to pull out the old keyboard and mouse just to sit in front of the TV and run some updates or install new software.  Many have turned to a feature in Windows known as Remote Desktop Connection. This feature, though only included in some versions of Windows, provides an easy way to connect to your Media Center form your everyday desktop PC.

Windows7 Remote Desktop Connection

Unfortunately, as long as you are logged into the Media Center no one else can use it.  This means that even though you may feel a little more comfortable the family still loses out on movie time. The solution is Concurrent User Sessions, allowing the Media Center to remain on the TV while letting another user in behind the scenes.

Thanks to the fine folks at Missing Remote  and friends, getting your Windows 7 machine to allow concurrent user sessions is as easy a running a simple command line program.  Just download the program here then right-click install.cmd to “Run as Administrator.” That should be all there is too it.

There are also a few command line options which can be run from either an elevated command prompt (type cmd into the start box and press ctrl-shift-enter) or a shortcut run as administrator. To enable blank passwords use “–blank”, “-multi” to enable multiple sessions per user.

Thanks to Missing Remote, Pinobigbird, untermensch and cocoa, we can now sit in the comfort of our well worn desk chairs to work on Media Center without disturbing the family (and incurring the wrath of significant others). Find the original article from Missing Remote right here.

Not working on the rc (build 7100) for me.

The install.cmd file from the above download won’t run on any build higher than 7000.

I tried it manualy and the termsrv.dll is not working…

Anyone found a version for the release candidate?

I seem to have it working with build 7127 now by changing 2 lines in the .cmd file. i assume this will work with further builds.

Hey Guys,

Has anyone tested this when also Media Center Extenders are part of the setup? I remember when I tried something like this on Vista (a few months ago), none of my extenders couldn’t connect to MC, so I had to revert it back…

i’ve ran this on w7 x64 RTM (v7600) and suceeded.

just edit the first few lines of the install.cmd file (notepad), and replace 7100 with 7600.

If you want multiple sessions for single account.
You would
run install.cmd -multi
But of course you cant just right click and run administrator if you if you want multi enabled.
Just go to start menu search for cmd right click on it and run as administrator.
Be sure to put the install.cmd in the desktop.
On the command windows opens in admin mode type
cd Desktop
so that you can change directory to the desktop.
on in the desktop just type
install.cmd -multi
basic cmd commands.
cd (change directory)
cd \ (change to c: root)
cd .. (go back one level, folder)
dir (list folder contents)
tab (autopleter) eg. type de then press tab it will complete with a match in the dirrectory, that would be “Desktop”.

It worked for me… I need to change the build-id to 7600. I did multi-user one too. However I don’t know how can I do multiple login of same user from different places ?
When I do remote login with same user. I see who logged in on my Media Center console, gets back to thelogin screen. I was expecting both user should have the same display like vnc ?

With all these comments and the article above it was not too clear, so I have listed what worked for me for Windows SP1:

1. Make sure you download the latest Win7SP1 version of the file called W7-SP1-Beta-RDP.zip located at http://www.missingremote.com/guide/sites/default/files/W7-SP1-Beta-RDP.zip

2. For this example, assume you unzip the file to c:\#install

3. If you have run this before rename the file C:\Windows\System32\termsrv.dll.bak to C:\Windows\System32\termsrv.dll.org or anything else different than the .bak extension.

4. Make sure the build number in your installCMD file matches that of your PC, to determine your build number type the following in a CMD prompt

REG QUERY “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion” /v “CSDBuildNumber”

5. You will get a response similar to this

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
CSDBuildNumber REG_SZ 1130

6. It is the 1130 that you are looking for, so now edit the INSTALL.CMD file that you unzipped from W7-SP1-Beta-RDP.zip and edit the 6th line

SET WINVER=Windows 7 Build 7601

7.You would change this from


8. to the following


9.So it would look like this (I removed blank lines for clarity but you don’t need to)

SET WINVER=Windows 7 Build 7601

10. Now you are ready to run the INSTALL.CMD file, which you must “run as administrator”

11. This is the typical output you will get


Source Folder is C:\#install\, Windows is 64-bit

Taking ownership of C:\Windows\System32\termsrv.dll

SUCCESS: The file (or folder): “C:\Windows\System32\termsrv.dll” now owned by the administrators group.
Granting Administrators rights
processed file: C:\Windows\System32\termsrv.dll

Pausing 5 seconds to give service time to start listening

TCP [::]:3389 pcname:0 LISTENING
Service is listening
Press any key to continue . . .


12. That’s it, now you can connect from a remote machine whilst you are logged on.

13. Enjoy

Thank you so much J Wilson for detailed descriptions, it worked…..:)

DJ, Make a user which is used to connect to remote system a member of Administrator group or RDP group then it will work.

Hi, this software recently stopped working when I updated Windows 7. It only seems to support Build 7100, do you know when the concurrent user sessions script will support the latest update?
