Start menu and windowed Metro apps
Today’s Windows 8.1 Update lets you default to the desktop and desktop programs when you’re using a proper PC. These are nice concessions to desktop users, as is the new system-wide taskbar that can highlight Metro apps.

Good news: Microsoft has already announced that both of those much-needed features are coming in future Windows updates. Just be aware that the reborn Start menu will mash up desktop functionality with Metro aesthetics
