Symptoms

When you play videos multiple times in Windows Media Player on a computer that is running Windows 7, a handle leak occurs in the Microsoft MPEG-2 Video Decoder. Additionally, the handle count for Windows Media Player increases continuously.

Cause

This issue is caused by an error in the MPEG-2 Video Decoder. A handle is created when you play a video, and the MPEG-2 Video Decoder does not release the handle immediately after it is created. Therefore, the handle count increases in proportion to the number of times that you play the video.

Resolution

    Version

    Product

    SR_Level

    Service branch

    6.1.760 1. 17xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    GDR

    6.1.760 1. 21xxx

  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
