N and KN EditionsAdditional Windows 10 editions specially destined for the EU, Switzerland, and South Korea (though South Korean editions have "KN") have the letter "N" (for Not with Media Player) suffixed to their names (e.g. Windows 10 Enterprise N) and do not have media-related technologies like Windows Media Player or Camera. There are N editions for all Windows 10 versions except Mobile, Mobile Enterprise, and IoT Core. Microsoft was required to create the "N" editions of Windows after the European Commission ruled in 2004 that it needed to provide a copy of Windows without Windows Media Player tied in. The cost of the N Editions are the same as the full versions, as the "Media Feature Pack" can be downloaded without charge from Microsoft.
Due to a ruling for anti-competitive practices by the European Commission in 2004, Microsoft has been forced to maintain special editions for its Windows operating systems. Labeled "N" for Europe and "KN" for Korea, these editions include all the base features of the operating system but without Windows Media Player and related technologies pre-installed. For the Windows 10 editions, this includes Windows Media Player, Music, Video, Voice Recorder and Skype.
总而言之这个版本是欧盟的反垄断的产物,是定制版,欧洲,瑞士和为N版意思是不带Windows Media Player,KN是指的Korea韩国其实和N版差不多,均为阉割媒体包的产物。2004年之后就有了这个版本,往上可以推到Vista N and KN版均类似。

Those editions lack at least the following functionality:

  • Play or create:
    • Audio CDs
    • Digital media files
    • Video DVDs
    • Organize content in a media library
  • Create playlists
  • Convert audio CDs to digital media files
  • View artist and title information of digital media files
  • View album art of music files
  • Transfer music to personal music players
  • Record and play back TV broadcasts after
  • Internet Explorer does not include playback for:
    • Adaptive streaming
    • Digital Rights Management (DRM)


It is possible to add the missing functionality with third-party software or with the Media Feature Pack, Groove Music and Xbox Video from Microsoft.

反正Windows 10 已经没有了DVD播放器,Windows Media Player的话N和KN版是没有的
