The problem with that is the same I’ve had trying to update an old MacBook my mother uses.
The patching tools work most of the time, but especially with Windows what happens when there is an update forced on you that breaks everything and you have to wait a few days and reinstall the whole OS again.
Most people don’t want that insecurity. And don’t tell me if it catches on in the slightest that Microsoft won’t do everything they can to break the patches.
Just look what John Deere did when people made 3rd party GPS devices for their farm equipment.
As much as I hate to say it for people who won’t use Linux isn’t there that version of chrome OS you can run on a normal x86 laptop. That’s a lot better then making a ton of landfill ( and it pains me to say that because I really hate Chromebooks, but that’s better then wasting tons of perfectly good computers).
