App: Windows Media Player 11
Issue: No Updates available, but some media when played cause WMP to notify user that an update is required.
Resolution: Click "Upgrade" and WMP will connect to a 'Microsoft' server and get the update.
Specifics: DRM protected subscription-service WMA music files require license/drm update for WMP 11, but the Help menu->Check for Updates command returns nothing. When a DRM-protected media file is played, it will then propmpt and download the require update.
Further: Microsoft (Windows) Update site does not list the update required, nor does WMP specify what the update is either.
