The Microsoft DirectX® End-User Runtime provides updates to 9.0c and previous versions of DirectX — the core Windows® technology that drives high-speed multimedia and games on the PC. 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.
- The DirectX end-user installation includes the D3DX, HLSL Compiler, XInput, XAudio, and Managed DirectX 1.1 components.
- Note that the DirectX Runtime (Direct3D, DirectInput, DirectSound) is not part of this package as it is included as part of the Windows operating system, and therefore cannot be installed or uninstalled. Updating the DirectX Runtime is achieved by installing the latest Service Pack or obtaining a newer version of Windows.
- For information on obtaining DirectX 11 for Windows Vista or Windows Server 2008, see Microsoft Knowledge Base article 971644.
- The DirectX End-User Runtimes installer contains all of the components installed by the Web Installer in a single package and is recommended for those users that do not have an Internet connection during installation.
