I have no idea what is on 11, but 7 is way more easy to use than 10, Eg to create a new folder on 7 I just click the new folder box, but on 10 I have to change to home and then create a new folder, and the replacement for the snipping tool on 10 is an abomination, compared to the one on 7.
Little things I know, but make 10 less easy to work with, when they didn't have to change it.
Far as I'm concerned they only stopped supporting 7 to try and force people to buy a later OS- just greed.
