The MSDN document you are referencing refers to Visual Studio 2012 , which has improved in the basic support for multiple monitors, which was first introduced in the 2010 version. This ability to group windows is probably the most significant of these improvements.
Unfortunately not in Visual Studio 2010 . At least not out of the box. It is available through the popular extension, Performance Power Tools . It massively updates the "Ub user interface" by adding floating tabs and many other features.
This extension has many features beyond taboo related ones. Since you install it anyway, I recommend trying some of them - you might like some of them. But you can also turn off the ones you don't like, which I consider the most important feature of all. After installing it, you will do all this in the "Tools → Options" dialog box in the "Power Tool Tools" section.
If you use the express version of Visual Studio that does not support extensions, or you are against installing any free tools that could make your life easier, you do not have many options. What you can do is unmotivate the VS window, stretch it to multiple monitors, and then attach tabs to the main window. You can even use horizontal / vertical groups if you want. This is cumbersome, but it works, we are used to doing this in versions until 2010.
