The easiest way to create or run a HTTP server in Windows is to use HFS. This handy executable file requires no installation or additional configuration. You just run the application, add the files you want to be shared and tell the user who needs to access your content and the IP that the program will give to you. By default, the application opens port 80 but if it's occupied, you can specify other port when clicking on the Port button. If your router has UPNP feature activated, your LAN server will be accessible from the outside.
