Yes, Linux would be fine for any number of users, many of whom need nothing more than a web browser. I suppose installing it would be too hard for most of them though (downloading an ISO, writing it to a USB stick and modifying a BIOS setting - tricky).
But if people insist that they need Windows, then they should accept the facts, and buy a new machine after Microsoft stops supporting their OS.
