Windows Aero (Authentic, Energetic, Reflective, and Open) is a GUI (graphical user interface) first introduced with Windows Vista.
Windows Aero include a new Glass or translucent appearance on the windows. Windows Flip and Flip 3D allow you to visually flip through each of the open windows to display that window. When a window is minimized, it will visually shrink to the taskbar, where it is represented as an icon. Aero also provides support for higher DPI.
To use the Flip 3D option, press the Windows key+Tab to switch between open windows in a 3D mode.
Windows 8 no longer supports the Flip 3D option. When pressing the Windows key+Tab, it switches between open Apps in the Switcher.
