Here are some websites that can explain what they are for that we found.
- “N” editions of Windows are available in Europe and are missing a few media-related features. On Windows 7, you’ll find that Windows Media Player and Windows Media Center are missing. On Windows 10, they don’t include Windows Media Player, Groove Music, Movies & TV, Voice Recorder, or Skype.
- “KN” editions of Windows are available in Korea. They remove Windows Media Player and related multimedia features, just like Windows N. When the KN versions of Windows were created, they also removed Windows Messenger. However, Microsoft has since discontinued this application.
