New features

 * When you hover over the top of a Metro app, Windows shows a title bar with minimize and close buttons.
 * Right-clicking on the Start screen opens up a menu instead of the touch-oriented controls at the bottom.
 * You can pin Metro apps to the taskbar.
 * A power button has been added next to the search button on the start screen.
 * SkyDrive is renamed to OneDrive (you can also get this in Windows 8 and Windows 8.1 RTM (without Update 1) by updating the SkyDrive app via the Windows Store).
