The biggest news in Windows 9 is the return of the Start menu. This is a familiar sight for Windows users and should go a long way toward getting things back to normal.
The Start screen is still there for mobile users and if you want it, but for desktop and non-touch laptop users, Windows 9 will default to the Desktop and Start menu.
Of course, this isn't quite the Start menu of yore. It includes the fancy live tiles like the Windows 8 Start screen, and a few things have been moved around. Still, it's a nice compromise and I think people will like it.
