For some reason this change was made with Vista. I know it has nothing to do with performance nor does it affect how Windows 7 works, but I too wish MS would provide a way to turn this back on. Windows XP did do it right in some cases, I have noticed if you have Themes turned on XP will act like Windows 7 at the logon screen and the second monitor will be dark, but if you turn Themes off then XP will display both screens at logon.
