My rule is to never change operating systems... everytime I buy a new laptop, it will come with whatever version is the latest. I simply can't find any reason to upgrade: at most it will have a small performance improvement, but the potential risk of messing up all my stuff, WITP-AE in particular, is to much for me
I really prefer to avoid writing in the "tech support" sub-forum as much as I can
Often performance degrades with a new OS because Microsoft doesn't put much effort into making new versions faster and they just bloat more and more. Most of my computers are desktops and I only use laptops for travel. I usually downgrade the OS to something I like better. My last laptop came with Win 8 and I immediately downgraded to Win 7. The one before that came with Vista and I downgraded to XP first thing.
I also configure Windows to look and act as much like Win 95 as possible. I didn't understand why until I started learning more about dyslexia. I'm mildly dyslexic and one thing dyslexics rely on is patterns. When the OS looks and feels like Win 95, I don't have to think about anything because the patterns are deeply ingrained at this point.
I have a friend who is severely dyslexic and she is even more dependent on patterns. Another friend who is an expert in all things Apple (he was a software developer there for a while) did some stuff with her iPhone and he arranged things in a way he thought was more efficient and she had a meltdown because the icons were not in the same place. He was bewildered, but I immediately saw it as a more extreme version of what I need. For her, she gets paralyzed if the interface changes too much.
My friend is a master at patterns though. She was studying fashion design and one of the things she had to do for one of her projects was do some sort of art thing that had no pattern to it. On the day it was due, she said she couldn't do the assignment because everything she tried had a pattern to it. The instructor said everyone else was able to do the assignment. My friend went through every assignment and pointed out the pattern in every one of them. She got an A on the assignment.
