I'm not a techie, my 7 does everything and more than I need it to do as it is. What's so "great" about 10 anyway ?
Our IT guy at work advised against W10 at the outset He said to wait. I trust him.
But eventually there will be no support for W7. Just like happened with XP...which I was perfectly happy with.
I suspect you said the same about XP before upgrading to 7.
