This is what bothered me the most when I last worked on MS systems (maybe 7 years ago now). As much as people complain about manpages, having a quick reference, with some verbosity, right at hand is immensely helpful. Maybe not knowing my way around the MS ecosystem handicapped me, but it was always so much more difficult to find a useful quick reference for what I needed in windows.
