This is a video of a user updating through every Windows release. Windows 1, 2, 3, 3.1, 95, 98, 98SE, 2000, XP, Vista, and 7.
This looks like a real consumer friendly design. Windows can be updated to a newer release without having too much trouble. But is this a bad design? Windows keeps getting more and more bloated with each release thanks to its insistence on backwards compatibility. And also on the Windows LNK vulnerability It was discovered in 2010 and it affects Windows from XP to the present 7. XP was 10 years ago! (Yes stop and think about that for a second, feels bad old).
