Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
DRM backup and restore permits DRM licenses that have the AllowBackupRestore right set to be backed up and then later restored to the same computer or to a different computer. When you restore DRM licenses, the player automatically contacts a Microsoft service to restore the license. You have to do this to limit fraud and to rebind licenses to the restoring computer.
