When preparing for the conference, I created a build environment from 
scratch, and followed our Wiki [1] to the letter (to test it). Then I 
learned that, despite the guidelines told about the requirement to 
install SDK 8.1 only, build process still required SDK 10 (I didn't 
install SDK 10 initially, and only tested without specifying any 
--with-windows-sdk ; in that case, the build failed until I have 
installed SDK 10). So actually I don't see a reason to default to that 
older version (mentioning about which I have removed from the wiki 
page). Possibly we even can't build without SDK 10 present at all? then 
I'd remove support for any older completely.
