I don't have Cygwin installed so I doubt that using its package manager
would make much sense for me.  Anyway, I suppose it provides a w32
executable, say emacs-w32.exe and some additional libraries.  I was a
bit confused by the term "package".

We would probably have to look at these "modifications" in order to find
out what happens.  Meanwhile a few questions:

(1) What is the appearance of the maximize button after step 3?  Does it
    show two overlapping windows or one large window?

(2) How do the frames from before step 2 and after step 3 differ?
    Please use M-: (frame-geometry) and post the ‘outer-position’ and
    ‘outer-size’ values.

(3) Apart from the problem you reported do

    M-: (set-frame-parameter nil 'fullscreen 'maximized)

    and clicking on the maximize button of the title bar produce frames
    with the same size and position?

(4) Does setting ‘frame-resize-pixelwise’ to t change anything?

(5) Can you try with a native Windows build or a GTK build and see
    whether they exhibit the same problem?

Can anyone with a native build on Windows 10 reproduce the problem?

Thanks, martin
