Port25 blogger MichaelF let us know that the technical preview release of Microsoft FastCGI for IIS6 and IIS7 is available for download in FastCGI and Zend Core 2.0.

PHP can work with IIS either by being installed with a CGI (Common Gateway Interface) or ISAPI (Internet Server Application Programming Interface).
