How to restart Visual Studio manually?

Question

Is there any way to restart Visual Studio 2010 (and possibly 2008 as well but not so important) manually and keeping the current state (i.e. all open solutions/projects and files)? Basically the same operation as when you install an extension and Visual Studio asks to restart itself. Occasionally Visual Studio gets confused after things like folder renames/moves, reference changes or the GUI editor throws a wobbly so it would be nice to be able to quickly restart the solution/project rather than close Visual Studio, reopen it and load the solution/project again.

I don't really like answering my own question but I found the RestartStudio extension for Visual Studio 2010 that adds the restart option to the File menu and seems to work well.
