When you view a Web page that has Microsoft Windows Media Player embedded in it, Windows Media Player 6.4 is embedded instead of Windows Media Player 9 Series or Windows Media Player 10. This behavior occurs even when Windows Media Player 9 Series or Windows Media Player 10 is installed on your computer.
This behavior occurs because the Windows Media Player 6.4 ActiveX control, Msdxm.ocx, was reregistered. The control may be reregistered by some versions of the Microsoft Internet Explorer Administration Kit (IEAK), by other applications, or by manual reregistering.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.

For more information about how to create programs that are based on the latest version, see the Windows Media Player Software Development Kit.
