User interface improvements
Windows Store apps are now easier to use for mouse and keyboard users: move your mouse to the top of your screen for the familiar functions of minimize and close; or move your mouse to the bottom of your screen to get the taskbar for fast app launching or switching. You can also access the taskbar from anywhere when you're using a mouse. You can see the taskbar on any screen by moving your mouse to the bottom edge of your screen, and you can pin your favorite Windows Store apps to the taskbar. If you like using the desktop, you will be happy to know that select devices will now boot to desktop as the default setting. For more information on these improvements, see Windows 8.1 Update – important refinements to the Windows experience.
