Similar happened to my parents years ago. Windows 7, working perfectly. My mum kept seeing a popup asking "do you want to upgrade to Windows 10?" and every time (for months) clicked close. Then, they changed the button layout and put a "install" button where the close button was, and she installed it without realising. Some bits of hardware weren't supported in Windows 10 and I had to go around and mess around with drivers, which I failed at. So, she's been on Fedora since. Considering all she did on Windows was light browsing in Firefox and many hours of Pysol, she barely even noticed the switch.
