For starters, the free "window" to Win10 upgrade has passed, so that probably answers most people's questions by default. Who's going to pay $100-$200 for a once-"free" OS?
Probably no one.
What should you do?
Here's a great take on Windows 10’s Free Upgrade Offer Is Over: What Now?
I could tell you to stay with what you have; or to move to Linux or Free BSD; but I wont do that.
I'll only tell you what I'm doing.
I use a PC as a tool.
Not-so-much for recreation.
So I want a "business class" PC.
I want it to work well and work fast (or, as fast-as-possible).
This is why I turn off all the "pretties" in Windows (sliding windows, mouse cursor shadows, transparent window borders, etc), and always use the Classic mode. Even if that only gets me 1% additional performance, I'll take it!
What is everybody else doing?
Well, I think this single pie-chart - an excerpt from the article linked above - says it all:
I'm staying with Windows 7 Professional, for now.
(Maybe full time Linux Mint after that?)
But that's just me. ;)
