Still No Start Menu
There's still no Start Menu (contrary to some reports of its return in Win 8.1), but in a blog post on TechNet Monday, Microsoft reported that it's working on bring it back in the "near future." In the meantime, the Desktop toolbar might be the next best thing. It's not new to Win8.1, and it's not enabled by default. It's activated by right-clicking on the taskbar and selecting Desktop from the Toolbars menu.
