Almost everything you need for a basic home web server is already in the Windows files that come with it... but to get it viewed from the outside world, you will need DNS server entry do people can find you. Here is a free Dynamic DNS system for a single name... great to learn and play with... https://www.noip.com/ I use DynDNS ( https://account.dyn.com/ and have 30 names/pages I can use ) and use their dynamic web server system since the IP address on our home routers is not a fixed number and can change. I can also grab my laptop and take it with me if I want to. The next step is opening a router port so you can receive the requests to your web server.
