Ubuntu on Windows

"Linux geeks can think of it sort of the inverse of "wine" -- Ubuntu binaries running natively in Windows. Microsoft calls it their "Windows Subsystem for Linux"."

I find it amazing that you can have such a functional Ubuntu environment by translating system calls. Microsoft does have the advantage of Linux being open-source I suppose, while the Wine project had to reverse engineer DLLs. Or have you supply them on your own.

I would rather have the opposite. I would even pay for an official "Windows on Linux". There is a handful of games I would like to play, but other than that I have no interest in windows.

Totally doable. Use KVM to virtualize Windows and (the important part) make sure your CPU and motherboard support VT-d. Then you can pass a graphics card (separate from the one you run Linux with, naturally) to the VM and get >95% of native performance. There's lots of videos of folks doing this.

I've heard that this works wonderfully for graphics, but the sound emulation is pretty terrible. At least, I've heard about clicks and pops when the game puts much load on the system. This was on a friend's machine; maybe he had it configured badly.
