MS4W sets that environment variable through an Apache directive; for IIS 
clients using MS4W, I always make sure to set System (not User) 
environment variables, and always always reboot the server manually 
after setting these variables (for some reason, whenever I set this up 
with MS4W on IIS I have to reboot the client's server for IIS to "see" 
them).
