where is php-cgi.exe?

I want to run php on windows7 within IIS. This MSFT document http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis-7/ has a step for adding module mapping to IIS for PHP. It says the executable should be "php-cgi.exe". I downloaded and installed the php windows binary ( x86, VC9 ) from the php site. The installer loaded php in \program files\php. But there is no php-cgi.exe on my system. Should it be there? If not, how do I config IIS7 for PHP otherwise? ( one mistake I know I made is to download the threadsafe version. The windows config doc says the non threadsafe version runs faster. ) thanks,
