I am not an expert but I would suggest to install a server if you don't have one yet. Most popular are Apache and Nginx. SInce official Odoo documentation have samples for Nginx that could be the way.

1. Download and install Nginx ( http://nginx.org/en/docs/windows.html )

2. Set the proper nginx config, you can find it in \here , just copy the entire config from the section named "Configuration Sample". Gzip config is in the last four lines:

 # common gzip
 gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
 gzip on;
}

Consider switching to Linux at some point as there might be some Windows-related cons.
