In the past month I have had to intervene 3 times to prevent a Win10 "upgrade". On Monday evening I found this "optional" update box checked-off as this article mentions.
Sneaky bastards. Now I am motivated to delete all those Win 10 upgrade files sitting on my local drive.
i did.
I need a Windows for dummies on this issue. Where do you go to see if your Win 7 was automatically changed.
