N and KN Editions
Additional 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 costs of the N Editions are the same as the full versions, as the "Media Feature Pack" can be downloaded without charge from Microsoft.
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.
