That’s a great option for her. Should Windows push a crappy update, she’ll still be able to use her computer.
My Lenovo Flex was okay at Win10. But I made the mistake of updating it to Win11 and it became a potato. I like my taskbar to never combine and at the right side of the screen so I could see all my open windows. Win11 killed that and I’m too much of a dinosaur to adjust to the “dock” taskbar type.
