My plan is to structure the article by first introducing Windows Server 2016, then detailing the build 14393.970 and its associated KB4016635 update, including the fixes it provided. Next, I will cover the upcoming April 2017 security update (KB4015217) and the critical MS17-010 (EternalBlue) vulnerability. The article will then explain the significance of the "2021" reference, discuss the supersession of this old build by later cumulative updates, and provide guidance for administrators. It will conclude with the support lifecycle for the operating system. I will cite the relevant sources, such as the Softpedia article for the fixes in KB4016635, the Microsoft Q&A discussion for the supersession note, and the update history for KB4015217.
