I have W7 on my laptop, and the laptop still hasn't downgraded to W10. One of my friends has recently (without her approval) automatically downloaded W10 and "couldn't do anything with it."
One major objection she had with it be that the start menu was difficult to use and navigate.
There's a fix for that with a free "Classic Shell" download that changes the start menu to a traditional Windows start menu.
