They also don't run animations in a separate process since Windows 10 which means that under high load everything lags. In Windows 8.1 everything was buttery smooth thanks to DirectUI. macOS and iOS also run animations separately.

I got so frustrated with how slow the file explorer got after my work laptop updated. Turns out the new UI is just shell extensions, if you add registry keys to redirect them to non-existent paths you get the old file explorer back.

Isn't this how pretty much every evolution of windows design has worked? at least from what I remember the windows 10 ui is built on top of aero (though admittedly I don't use windows and have never interacted with it for anything serious)

This is even more insane than I thought. Truly madness. Everybody involved with that should be fired and sent to the moon as an experiment on how long does the human body survive naked on both the dark side and the bright side of the moon. At least we will learn something from those experiments.... (it's a joke but the point stands. Those people shouldn't ever be allowed to touch computers.)
