Microsoft DirectX is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full-color graphics, video, 3D animation, and rich audio. DirectX includes security and performance updates, along with many new features across all technologies, which can be accessed by applications using the DirectX APIs. At the core of DirectX are its application programming interfaces, or APIs. The APIs act as a kind of bridge for the hardware and the software to "talk" to each other.
The DirectX APIs give multimedia applications access to the advanced features of high-performance hardware such as three-dimensional (3-D) graphics acceleration chips and sound cards. They control low-level functions, including two-dimensional (2-D) graphics acceleration; support for input devices such as joysticks, keyboards, and mice; and control of sound mixing and sound output.
Because of DirectX, what you experience with your computer is better 3-D graphics and immersive music and audio effects.

Additional Information:
- The DirectX redist installation includes all the latest and previous released DirectX runtime. This includes the bi-monthly D3DX, XInput, and Managed DirectX components.
- The DirectX runtime cannot be uninstalled. We recommend Windows Me and Windows XP users create a "System Restore" point before installing.

Simply put, DirectX is a Windows technology that enables higher performance in graphics and sound when you’re playing games or watching video on your PC.
