> What "modern software support" do I lack here?

There is a growing list of software that which has discontinued support for Windows 10 on the latest versions (or the Server versions thereof). I'm not sure if your example of running a ~16 year old version of SQL Server on Server 2016 demonstrates.

To my original post - if you only need to run an old version of a software package, then an old version of Windows is fine. Just because something is old, it doesn't mean that it is not useful.
