I could see the argument that 7 was peak, but I think it was XP. My Dad pretty much downloads pictures from his phone and browser the web. One issue is some of the sites he uses are set up weird. That why he finally allowed me to upgrade him from 7 to 10. He complained about certain sites, which I really didn’t pay attention to which, would give warning about browser being out of date, then the sites refused to even load. That is when he allowed me to upgrade. They probably would work but I don’t want to risk issues with any sites having problems with Linux.
