Please provide a reproducible recipe starting with "emacs -Q".  Just
typing "C-x C-f con TAB TAB" doesn't show CON in the completions, so
I'm unsure how you bump into this problem.

Well, then don't do that, right?  There cannot be a usable file by
that name on Windows, so why would you need to try visiting it?
