Windows now runs Linux binaries.
Hopefully it works better than last time.
You can run an entire Linux DE now naively under Windows
Well, according to Wikipedia, the new Windows Subsystem for Linux cannot run graphical applications. I guess you can get around this by running a separate X server for Windows. I used Cygwin's X server years ago with good results but it looks like some people have had trouble getting more complicated applications to work.
On the bright side, maybe this means we can finally install systemd on Windows 10! One can only imagine what their combined powers are capable of.
