"For example the relative infrequency I print something means I do not check the printer with every OS update of any OS"
This points to another big problem with Windows 10. If you discover an issue with something you don't use regularly, you really have no idea what to try to roll back to to fix the issue!
Before Windows 10 at least you knew if you had switched from Vista to Windows 7, for example. Also, after OS upgrades one could test what worked and didn't.
