Concurrent Windows 7 Sessions (Pro, Ultimate, Enterprise)

If you are like me, you want to be able to login to your computer as many times as you see fit and not be limited to a single session. This has nothing to do with wanting to allow hundreds of people to use your computer but rather to be able to run tasks at the same time that otherwise wouldn't be possible. As an example, perhaps you want to run some file backups while your son is watching a movie. Or maybe you want to print something form your desktop but your daughter is doing her homework and you don't want to interrupt her.

What ever the reason, the reality is that people need to be able to login concurrently to one computer. I have to warn you: Enabling concurrent sessions in Windows 7 Pro, Ultimate, and Enterprise is actually against the end user license. So by doing the following, you will probably be breaking that agreement.

 So let's get started:
 Step 1: Download the termsrv.dll patcher
Step 2: Run the patcher as an administrator
Step 3: ???
Step 4: Profit

 In all seriousness, the patcher essentially takes care of all the heavy lifting. There are other options you can change through the group policy editor that will allow you to take control of other sessions, and even shadow those sessions unbeknownst to the other user.

To see some of these settings, navigate to "Edit Group Policy" in the start menu. Within the group policy editor, navigate to the following items:

Computer Configuration
-> Administrative Templates
--> Windows Components
---> Remote Desktop Services
----> Remote Desktop Session Host

From here you can modify settings like "Set rules for remote control of Remote Desktop Services user sessions" aka shadowing.

Note: The above instructions were working as of March 2013, using the most recent builds of Windows 7 Pro, Ultimate, and Enterprise editions. The patcher was tested with 64 bit versions of Ultimate and Enterprise, however it should work with 32 bit. I am not the creator of the patcher file. You can find that creator within the file itself.
