The problem with Win 8.x is it's a touch or tablet OS. The mouse and keyboard model was ignored. One thing you have to watch with Win 10 is it talks to the mothership a lot. Lots of this stuff can be turned off by not using express settings in setup. There are numerous tutorials on how to turn off monitoring, although most seem like complete overkill. Search has settings allowing users to turn off internet searches from the search box. That makes searches less annoying and more private.
If you just don't like Win 10, Microsoft will be supporting Win 7 through April of 2020. It is currently the dominant desktop/laptop OS with over a 60% market share. XP is fading fast and is down to 11%. New Win 7 installations are a bit of a headache due to the huge number of updates required and spotty native driver support for recent hardware.
The printer drivers for my crappy Canon inkjet migrated without any problem. Win 10 uses the same driver model as Win 7, but this isn't a perfect world.
