Actually, it is still an org issue, albeit one which requires input from
those with much more Windows knowledge than I have.  It's an org issue
because I think we do (or should) strive to have org, as a whole, work
on any system that runs Emacs?  

There are only two arguments to the maxima invocation above:
=--very-quiet= to minimise the amount of superfluous output and =-r= to
ask maxima to execute the following maxima command ("batchload(...)")
which is what tells maxima to execute commands from the file that babel
creates.

If you (anybody) can figure out the magic incantation necessary to
invoke maxima on Windows and have it execute commands from a file, it
should be straightforward to upgrade the =ob-maximal.el= file to use the
right incantation depending on the operating system.
