The reason might be SBCL - a Lisp-Compiler, which is included and used 
by Maxima:

If that is correct, there is an easy solution: The Maxima Windows
installer is compiled with two different Lisp versions; SBCL and CLISP.

There is a tool included, where you can select, which Lisp version
should be used by default ("Configure default Lisp for Maxima" in the 
start menu).
There select CLISP. It is slower than SBCL, but should work on Windows 7
and it has better memory management than SBCL.

Or you can select the used Lisp in the wxMaxima configuration: In the
'Maxima'-Tab enter "-l clisp" as addtional parameters for Maxima
(without the quotes, of course).


Or use an older Maxima version. According to the Git version control
system Maxima 5.45.1 included SBCL 2.0.0, which (if the above bug report
is correct) worked on Windows 7.

Hope that helps.
