I'm still on 7
I never took up the offer to the "free upgrade" to 10
I'm glad I didn't
my mother in law in Melb has 10, so I use it when I'm down there
I find 10 not very intuitive, a bit "clunky" and downright frustrating at times
7 just works
windows 8 through to 10 was designed primarily for touch screens and that is the main reason I was never very interested in the so called "upgrade"
another reason , I usually do a windows fresh install once a year, and without an actual hard copy of the operating system it makes things difficult for me.
7 is good til 2020
I'll reassess my options then
