I have W10 on all my computers.
Very little to no problems with it. In fact, it made my 10 year old Acer work MUCH better.
Just because folks don’t know how to use it, does not make it bad.
Besides, they can always go to linux if they don’t like it.
And I bet the EULA will shoot anything these folks can do down quick.
So happy with Win 7 Pro 64.
