Aero Lite

Aero Lite is the name of the hidden visual style that debuted in Windows 8 and is used within future versions of Windows. The msstyles file but not the theme file is present in the C:\Windows\Resources\Themes\aero folder in Windows 8/8.1/10. To enable the theme, create a copy of the aero.theme file called aerolite.theme and redirect it to the aerolite.msstyles file and set its display name to Aero Lite.
