Rather than move ExtraPackages/Enhancements from my separate AddOns 
directory (outside the $TopDirectory tree), I appended ExtraPackages to 
$Path by an AppendTo statement in ToFileName[{$BaseDirectory, "Kernel"}, 
"init.m"].

Note that I used the Windows system variable MATHEMATICA_BASE to point 
to that separate AddOns directory.  (I did not also set 
MATHEMATICA_USERBASE to point there, since that has the unpleasant side 
effect of the names of all my pallettes in that separate AddOns 
directory appear twice on the Mathematica File > Palettes menu!)

Thanks to all who replied to my original posting.
