SUMMARY
This step-by-step article describes how to include a program that is incompatible with the Windows Media Player 9 Series control on the bypass list. A program on the bypass list does not start the Windows Media Player 9 Series control if otherwise coded, and makes it possible for the program to work correctly. Windows Media Player 9 Series includes a compatibility layer makes it possible for programs that use the Windows Media Player 6.4 or earlier control to use the security, privacy, and technology enhancements that are included in Windows Media Player 9 Series. The compatibility layer has been tested in a number of scenarios. However, you may notice differences when you view Web pages or audio and video content in other programs after you install Windows Media Player 9 Series. For example, video may not play properly, or may not play at all, and programs that do not start properly. If you experience problems with programs that use the Windows Media Player 6.4 or earlier control after you upgrade to Windows Media Player 9 Series, this may be caused by the compatibility layer.

To work with incompatible programs, Microsoft has created a bypass list that lists programs that are based on older controls that do not work correctly after you install Windows Media Player 9 Series. This causes the original Windows Media Player control to be invoked. Although this makes it possible for the program to work, the program and the user do not benefit from the security, privacy, and technology improvements that are included with the Windows Media Player 9 Series control.
