There's a site called Apache Lounge that has put together a collection of binary files for Apache for Windows. What's notable about these is the inclusion of the SSL module, which the Apache Foundation don't distribute in their Windows binaries anymore. Along with the core Apache install they also have some some plugins/modules for Apache that are worth using - a log rotator (so that the traffic log doesn't fill your drive), an interesting looking security plugin, and updated plugins for PHP and Perl. Well worth keeping an eye (and a bookmark) on if you use Apache on Windows.
