That's incorrect. Many changes have been made to PHP over the past 1.5 years to make it run faster and more reliably on Windows. All those patches have been contributed to the PHP source tree. So it's a combination of the FastCGI work Microsoft did and improvements in PHP which make this a viable option for running PHP applications.
That is exactly the point. There are very few Windows deployments because PHP on Windows was 2-3 times slower than on Linux and unstable before we made the said improvements in PHP and Microsoft built FastCGI support into IIS 7.
