So "Linux on Windows" isn't really happening here. Binaries intended to run on Linux are just being tricked to run on Windows -- basically the same as Cygwin, with the minor benefit of not requiring a recompile.

  That is quite a bit different from Cygwin. Running the Linux kernel on Windows has been done before IIRC - coLinux?

    That's what I was thinking but coLinux never did 64-bit

  It's a lot more than that. When Cygwin is built, the translation between to POSIX is handled via Cygwin.dll with the various tools recompiled against that file. This version is taking the native Ubuntu binaries and executing them directly against the Windows API via a real time translation later. The difference is like playing a game using virtualization technology vs. WINE. As the complexity of the game increases, the former begins to slow down and break.

  "just" You don't have to be a fan of Microsoft but they deserve at least some credit.

  Cygwin is pure userland. This Linux API subsystem is a small bit of userland (similar to kernel32.dll in the Win32 subsystem), but mostly kernel code.
