How to set the guides (right-margin marks) in VS2012 text editors

Question

Is it possible to set the guides (right-margin marks) in the visual studio 2012 text editors without any extensions?

Edit: registry key HKCU\Software\Microsoft\VisualStudio\11.0\Text Editor doesn't work. Any working solutions?

Answer 1

Now is the Paul Harrington's Editor Guidelines Extension for the Visual Studio 2012 available. So you have an extended context menu, where you can Add, Remove or Change Color of the guidelines.
