Users less than happy.....
Not the ones I have come across. 75% are LESS then happy. Windows 10 is a buggy mess that fixes some of the windows 8 mistakes, but is still huge downgrade from Windows 7
I'm not complaining, I get 3 or 4 calls a day from botched free upgrades that no longer connect to the internet and need network settings and drivers fixing. I'm quids in. I guess many other windows 10 champions also have financial motives too.
