DirectX is Microsoft's name for a family of application programming interfaces designed to speak to multimedia programs, such as music and video players. The DirectX family includes Direct3d, DirectMusic and DirectPlay and the "X" stands in for the name of the individual program. In addition to applications in the Windows operating system, Microsoft also uses DirectX in its Xbox video game system. Older versions of DirectX may not work with newer multimedia applications. If you find yourself receiving errors in your multimedia programs, you may need to check your Direct X version to determine if you are up-to-date.

Steps

Find DirectX Version on Vista

Click on the Windows icon in the bottom left corner of the screen.

Type "Dxdiag" in the space labeled "Search Programs and Files." The DirectX Diagnostic Tool window will launch.

Click on the "System" tab. The tab may be the first to present when the DirectX Diagnostic Window opens. If not, it should be the first tab on the top left.

Look on the system tab for a section labeled "System Information." Scan down to the bottom of the list for a section labeled "DirectX Version" where you should see your version.
