> Migrate Windows to the Linux kernel and get Linux compartibility out of the box

If I had a quid for every time I saw this comment on HN or Reddit I would probably be as wealthy as Gates himself. It is always an instant downvote for me, because they make me lose faith that people on HN have actually understood what a kernel is and how it works, and what ABI compatibility is, and what user-mode stability is. It is dogmatic and pointless.

The NT kernel is pretty good. Windows is generally well-architected. The NT kernel is the best thing about Windows, and you lot want to swap it out with something decidedly inferior.

Windows' user-mode applications and libraries are also pretty good. By user-mode apps and libraries I mean Win32 itself, WinRT, D2D/DirectWrite, D3D, Winsock, Windows Sound, and the thousands of entrypoints and enums for cool Windows stuff like the registry, synchronisation primitives, file management, special user files, cloud files, accessibility and internationalisation, and more. I've mentioned some other nice platform APIs in a sibling comment.

It is pretty easy to write a full-fledged GUI application on and for Windows that handles heavy use of networking, sound, graphics acceleration, etc without ever having to use a single third-party library, and make it run on OSs that are nearly 18 years old (not the case on most competition OSs).

I also daresay that IE/Edge moving to Chromium was in some ways a bad idea, as Chromium has become the de facto default Web platform, and any non-Chromium browser (Safari, Firefox) is likewise de facto non-conforming.
