Microsoft Knowledge Base (KB) article 2835517 redirects you to this article. This article describes Media Feature Pack update 2929699, which supersedes the previously released update 2835517. In addition to update 2835517, this update also applies to Windows 8.1 Pro N/K for EDU and Windows 8.1 N/K with Bing.


The N and KN editions of Windows 8.1 include the same functionality as Windows 8.1, except for media-related technologies (Windows Media Player) and certain preinstalled media apps (Music, Video, Sound Recorder, and Skype). You must install other software from Microsoft or another company for this communication functionality and to play or create audio CDs, media files, video DVDs, stream music, and take and store pictures.

Some websites and software, such as Windows Store apps or Microsoft Office, use Windows Media-related files that are not incorporated into these editions of Windows. End-users can make these websites and software work correctly by installing the Media Feature Pack for N and KN editions of Windows 8.1 (KB2929699).
