The implementation of this effect is mainly called the Dwmapi.dll of the system.

Dwmapi.dll is a dynamic-link library of the Microsoft Desktop Window Manager API (the common interface of the desktop Windows Manager dwm), a normal file that is primarily used as an API for desktop effects.

The DWM is a new interface that provides the DWM interface in all versions of Windows Vista except Windows Vista Home Basic. So this effect can only be used in a system after vista.
