Hi John,
Thank you for writing to Microsoft Community Forums.
We understand your concern and we appreciate the time and effort that you have taken to research and performing the registry changes regarding the issue. However, we would suggest you to provide your feedback and suggestion in Send feedback to Microsoft with the Feedback Hub app as MusicMatch-ssl.xboxlive.com is the latest service to update metadata of albums. Going forward, you may be unable to view information (metadata) such as the title, genre, and artist for songs, and the director, actors, and cover art for movies in Windows Media Center and Windows Media Player. After looking at customer feedback and usage data, Microsoft decided to discontinue this service. This means that new metadata won’t be updated on media players that are installed on your Windows device. However, any information that’s already been downloaded will still be available.
You may also want to refer Changes in metadata service affecting Windows Media Center and Windows Media Player for more details.
Regards,
