Consider the following scenario. You install security update MS07-068 on a computer that is running the following items:

In this scenario, Windows Media Player might no longer correctly play some media files. For example, Windows Media Player might not play .mp3 files correctly.
To resolve this problem for Windows 2000 users who require .mp3 functionality in Windows Media Player, we recommend that you upgrade to Windows Media Player version 9 or to a later version. Updated versions of Windows Media Player are available from the Microsoft Download Center, from the Windows Media Player Web page, from Windows Update, or from Microsoft Update.
