More Information


If the issue still occurs after you install the hotfix, you can perform one of the following actions:
  • Make sure that the music library is fully rebuilt before you exit Windows Media Center or Windows Media Center Extender.
  • Disable the media streaming or the media sharing feature in Windows Media Player. To do this, follow these steps:
    1. Open Windows Media Player, and then click Stream.
    2. If you see the "Turn on Media Streaming" option, media streaming is already disabled. Therefore, you do not have to continue to step 3.
    3. If you see the "More streaming options" option, click this option, and then click Block all to prevent everyone from playing your media.
    4. Click OK to apply the change, and then close Windows Media Player.
  • Prevent Windows Media Player from retrieving related media information from Internet. To do this, follow these steps:
    1. Open Windows Media Player, click Organize, and then click Options.
    2. Click the Privacy tab, and then clear the Update music files by retrieving media info from the Internet check box.
    3. Click OK to apply the change, and then close Windows Media Player.

Note This issue may occur when you add new assets to the music library.
