Hi, lurker here. Watched the latest chat and wanted to comment on Windows 10 updates.
I'm using WUMT (Windows Update Minitool) and have been using it for last 1,5 years.
Take a look at

The only thing is that it has not been updated since 2016, but it still works. Essentially: Disable the automatic updates (using GPOs or just disable the Windows update service). Then you can use the WUMT to select and install whatever updates you like - just like in the older days.
However: Microsoft these days just bundles everything together in "Cumulative update for January 2019" and similar packages. So you cannot really pick and choose some specific KB. Still, the control is there.
