How to start Windows 7 application "recent session"?

How to start Windows 7 application "recent session"?

Here I'm NOT referring to just starting a Windows application. What I want
is to utilize Windows functionality of "Recent sessions" which can be
visible for example here:
I'd like to know how to start those recent sessions programmatically when
I know the name of the session.
So far my own searches only leaded to loads of articles on starting the
applications - but no description of specifically "Recent sessions"
mechanism.
UPDATE:
Seems I was not clear enough. I know that from my C# application
(WinForms) I can start external processes using something like:
using System.Diagnostics;
...
Process process = new Process();
// Configure the process using the StartInfo properties.
process.StartInfo.FileName = "process.exe";
process.Start();
My question actually is: Is there any way - by specifying any options of
process.StartInfo OR by using any other possible way to start external
process - to start not just an external application, but a "Recent
session" of this external application if I have this "Recent session" name
already.
