In VS2008 this could be done easily, it was just required to modify the registry.

Visual Studio 2010 lacks this feature, but there is a cool plugin for that:
Editor Guidelines.

Just download, install, and put the following code in to the registry:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USERSoftwareMicrosoftVisualStudio10.0Text Editor]
"Guides"="RGB(255,0,0) 80"

There is a hidden feature in Visual Studio. You can add a nice, red, vertical line to your editor.

All you need to do is to create a .reg file with the following content:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER/Software/Microsoft/VisualStudio/9.0/Text Editor]
"Guides"="RGB(255,230,230), 80"


And add it to registry (double click). That’s it!
