I don't think your kernel of choice is of direct interest here; I'm fairly certain what you're interested in is access to your familiar tools, which the "Bash on Ubuntu on Windows" system would potentially provide.

As for a POSIX sub-system on Windows, well there once existed such a system that was near-compliant, but MS stopped supporting it a few years back. As for Wine, I think cygwin fulfills a similar role.

Anyway, you want your tools. You might even want your familiar filesystem and its hierarchy. I think the primary reason Microsoft deemed it worth it to implement Bash on Ubuntu on Windows was to provide webdevs access to the same tools they had on osx/linux.

All in all, I think a bit of reading on these subjects would help, because I think you're confusing the kernel with the userland.

Note: I'm faily young and inexperienced, and when I heard the "Bash on Ubuntu on Windows" announcement, I didn't really know what the meant. But learning about these bits on wikipedia/various blogs was certainly interesting.
