WSUS refers to "Windows Server Update Services" which is a software provided by Microsoft to help systems administrators to manage Windows and Microsoft products in a corporate environment.
Think of your Windows 10 computer updates, but for Windows servers and how you would want to manage the approval of updates, timing of updating, etc. within a centralised system.
This guide is to show you how to run similar commands using Microsoft's Visual Studio Code environment.
As Visual Studio Code is also free. Built on open source and runs everywhere. The biggest benefit I can see is the availability of extensions which can further enhance your programming and testing experiences.
You may be using Postman, Terminal or another tool to run some of your API testing and various commands. This will be similar.
