I am one of those with a laptop that I upgraded from win7 to Win10 and it went smooth. But wife was only playing a few facebook games and it got so bad with freezing that she wanted me to revert back to Win7. I did that 2 days ago (reverted back without a glitch) and she has not had a problem with anything since. I guess Windows 10 is still full of bugs for some systems. I am sure I will upgrade the laptop at a later date to see if those bugs are fixed.
