I wouldn't be too sure about not running servers on this. Plenty of places really really want to have a standard build of windows on all their servers without exception. Plenty of developers want their stuff to run on a well understood LAMP stack that isn't a complete and utter pain in the arse to install and update. WSL lets everyone be happy - not sure it can run background services properly yet, but there is certainly a use-case for it running servers. Now whether such a machine is vulnerable to this kind of exploit is a bit of an open question. This seems to be describing a potential privilege escalation by writing into the memory of Linux applications, which seems like something that shouldn't be allowed by the windows kernel.
