Currently openssh tests for a TTY by opening /dev/tty which does not exist on Windows. It most cases this then falls back to a prompt that works, but if the DISPLAY env var is set, then it tries to spawn "/usr/X11R6/bin/ssh-askpass" and fails - see issue #966, #1515, PowerShell#762, #1088, #1356, and probably others. Possible workarounds are to create a file `C:\dev\tty` so that it is able to open it, or to unset the DISPLAY variable, but it would be better if OpenSSH could detect this is a valid console. Code is from PowerShell/Win32-OpenSSH#966 (comment)
