Various computers in our house are running Windows 10, and it's been great for us on all of them - no problems at all.
However, my main editing computer is W7, and like you, it's offering me the upgrade. And I'm resisting it. Everything is working perfectly on that computer, and that computer is SO important to me, so I'm not willing to change anything just for change's sake.
That's just my two cents. This isn't even my section, I'm not supposed to be replying here
