I've been using 10 since the day it launched and honestly have no advice because it's virtually indistinguishable for me from Windows 7. I noticed practically zero difference. Turn game mode off I guess, that supposedly does more harm than good.
If you're not super into techy or privacy stuff then you'll probably be just fine.
I still use both Windows 7 and 10 side by side on two separate PCs (as well as Linux Mint 19 & 20 XFCE, Raspbian Linux, even Windows XP (but that is just for playing some older games)).
I agree with "you'll probably be just fine", but I don't agree that Windows 10 is virtually indistinguishable from Windows 7. The user interfaces are quite different (e.g. the start menu and how it doesn't have subfolders in Windows 10, how Windows 10 has this split-brain syndrome where some of the stuff are in the "new GUI" and some stuff in the older, Windows 7-like GUI).
So there are some GUI changes to learn when coming from Windows 7, but nothing unbearable.
