When I start an application like the Windows Explorer I see, above the
title bar, the upper border of its window.  When I maximize the
Explorer's window, I still see the title bar, but the upper border has
disappeared.  When I make the Explorer window fullscreen (via F11) title
bar and upper border both disappear.

No idea.  But with Emacs I can maximize a frame and do

(set-frame-position (selected-frame) 12 12)

to move it, keeping its previous size, while

(set-frame-position (selected-frame) 0 0)

will move it just for a short moment and back to the previous state
afterwards.  In any case, I can clearly see that the frame keeps its
outer borders, confirming an earlier claim of Juanma.

I can't elaborate because I don't know what you tried to do when you
reported what you saw.  Here I cannot move a maximized Emacse frame by
dragging the mouse or via the System Menu.  I can move it by evaluating

(set-frame-position (selected-frame) 12 12)

or resize it by doing

(set-frame-height (selected-frame) (1- (frame-height)))

though and there's still a button enabled telling me that I can "restore
its size" so Windows still thinks that the Emacs window is maximized.
There's one funny discrepancy: I can't mouse-drag the moved window but
can drag the resized one.

Not necessarily.  I unfortunately lost my Emacs trunk version and am not
sure whether and when I'm able to recuperate it, but IIRC I had lots
of incoherent states after doing M-F10.  But, maximizing Emacs via the
button in the upper right corner (I never use that but call WinMaximize
via a key combination instead) always works as expected.
