Microsoft is warning organizations about the impending end of support for several Windows products from 2016.

Extended support ended for Windows Server 2008 on January 14, 2020. It was possible to keep the lights on until January 10, 2023, via Extended Security Updates. A fourth year came courtesy of Azure, which took the code to January 9, 2024, but that was it for anyone without PA.
