Update 2018-04-20: I’ve rolled the information in this post, and updated it, into a new post about setting up a WSUS server from scratch on Windows Server 2016 Core. The post is also suitable for a regular Windows Server 2016 server with a GUI. You can read it here. Update: I’ve tested and updated this post for Windows Server 2016. In this post, I’m going to walk through setting up a WSUS server from scratch on Windows Server 2012 R2 or Windows Server 2016.
