Aero Lite

Aero Lite is the name of the visual style that debuted in Windows 8 and is used within future versions of Windows. This design was first introduced in build 7850, although it's a slightly altered Aero theme. Changes became more notable with build 7989, which gave the theme a more basic rectangular design. Windows transparency was also removed in this theme and this theme could run without requiring a driver with WDDM.
