Configure Apache 2 on Windows With Prefork MPM

How do I configure Apache 2 on Windows so that it uses the Prefork MPM? The default installation of Apache 2.0.54 comes with mpm_winnt loaded, but not mpm_prefork. I want to run prefork because the current PHP installation file recommends using it, because some PHP libraries are not thread-safe. The Apache documentation doesn't seem to answer my question. I have Apache 2 running on Windows now, I just don't know how to change it to use the prefork MPM.
