You need to decide what Operating System will host your Web Server. Linux or Microsoft Windows are popular choices. I have used them both, and I have to say that Windows is the easier way to go. I love Linux, but its file system (in particular file permissions) can be daunting and confusing. It will also bury your Apache files in somewhat obscure directories. Before Windows 10 came along, licensing was a big pain with Microsoft, but Windows 10 will run just fine without a license. Our end goal here is to host a WordPress site, so we need a WAMPServer (Windows, Apache, MySQL and PHP) or LAMPServer (Linux, Apache, MySQL and PHP).
