Note the installation order information for Windows Server that Microsoft provides in the KB articles. Windows 7 and 8.1 are out of support in January 2023, but Windows 7 systems can be provided with security updates via updates. See my notes on Windows 7 ESU and BypassESU v12 in the blog post Microsoft Security Update Summary (February 14, 2023).
