Alex Netkachov as a (very) quick note posted today involving the update to IIS' FastCGI and Jamp!:

Go Live FastCGI for IIS release was announced and I've added is to Jamp!. PHP.IIS command now can install PHP on IIS over FastCGI or over ISAPI filter.

Jamp! is an easy installer for a Java, Apache, MySQL and PHP setup. It makes it a simple, one-click operation to get it up and running. Get more information about the installation and downloads from this post.
