That is a complete rewrite of your original comment, Windows N is about a lot more than a few codecs, it excludes Skype, Windows Media Player and other media playback applications. Your claim was that Windows 10 only sells in N editions which is blatantly false.

Not really. The reason the EU wanted Windows N was to avoid users having to buy a bundle (the EU really dislikes bundle pricing). Skype is gone from all Windows 10 installs, and while WMP was able to access lots of special APIs, Groove (which is the only media player bundled on Windows 10) uses the same APIs as every other program, and relies on the same preinstalled codecs.

This provides the same situation as with Windows N: No Bundle pricing, no Microsoft programs having any special access.

Not at all, the N spring from the anti competitive ruling in EU courts (2004 with associated fines) saying that MS couldn’t bundle WMP with a near-monopoly on the market. The condition was that MS was allowed to sell it with WMP as long as they offered a version without it (that’s Windows N). This has been the case since Windows XP N.

Windows 10 comes with Skype pre-installed.

I’m starting to think you’re merely guessing instead of actually having used Windows 10, because nothing you’ve said so far has checked out with actual installations.

You can just go to the Microsoft store and you’ll see “Windows 10” and “Windows 10 N”, which should be sufficient enough to prove that not all Windows 10 are N editions.

I've got Windows 10 here, german EDU edition, and no Skype or WMP is preinstalled. Groove is preinstalled, but can't play anything at all without installing separate codecs.

Ok so that explains a lot, and has nothing to do with Windows 10 as a whole (which has a separate N edition as every Windows since XP).
