Some of the key features of Windows Aero include a new Glass or translucent appearance to each of the windows, as shown in the image to the right. Windows Flip and Flip 3D allows you to visually flip through each of the open windows to display that window, instead of a simple icon like previous versions of Windows. When minimizing windows, the window will visually shrink to the Taskbar. Aero also provides support for higher DPI and smoother performing windows.
Note: Windows 8 no longer supports the Flip 3D option. When pressing the Windows key + Tab, it will switch between open Apps in the Switcher.
