The full page of my Nginx for Windows builds are located here: Nginx For Windows.
Native Nginx Windows builds are available at http://nginx.org
nginx 0.7.4 for Windows was built on Vista Ultimate 32-bit and is known to work on Windows Vista, Windows XP Professional and Windows 2000 Professional.
nginx was compiled using Cygwin. If you have any other instance of cygwin1.dll on your system, you may have a conflict that won’t let you run nginx. Remove any Cygwin1.dll files and it should work.
