The more sensible take is “don’t use new technology where it doesn’t make sense.” The start menu should need a web browser engine and a heavy JS framework because…?
Well I don't use Windows so I can't comment on the quality. And I actually don't even really care about it. I was just commenting on the curmudgeonly perspective that young people can't do things right.
Another way to look at it: Microsoft APIs have fallen from grace. Even their own devs don't dogfood anymore. They download something that Facebook made instead and reimplement the Holy Start Menu using that.
