OK, let's focus on this problem.

Your original report, written on February 22, said that the problem 
started after the latest Cygwin update.  That means you would have 
installed emacs-25.1, if Emacs was updated at all.  But I've just 
checked that the problem already exists in emacs-24.5.  So maybe the 
problem was triggered by an update of some package other than Emacs, 
Mintty being the most obvious guess.  Can you check your 
/var/log/setup.log to see what was updated around February 22?
