Windows 11 (the UI/shell at least) is so unbearably slow that nobody would want to run it on older devices anyway.
I get rendering changes: taskbar buttons are squares without text now, it uses transparent effects, etc. Or the Start menu having different containers inside, though I'd still expect each UI container to behave speedily. What I don't understand is the delay clicking in the search field, or why right-clicking a taskbar button has a perceptible moment before the context menu appears. What have they changed? Is it built with one of their new UI .Net layers, or WinUI3? Is it a custom menu implementation that someone wrote without thinking they reinvented the wheel? What on earth is going on?
Also a fun one:
There are two cloud drive clients, one uses WinUI and is snappy using ~100MiB of RAM, another one is written with React Native and uses ~250MiB of RAM. Which one is written by Apple and which one by Microsoft?
After suffering through it long enough, I downgraded it back to 10 with a fresh install and it felt like a different device.
I feel a little bad for Microsoft. They clearly believe they have to find new things to add to their OS for the sake of adding things and justifying the upgrade. And this is likely just from teams that want to show impact (i.e. keep their jobs).
Win 10, for all it's faults, has served me well. I'd be happy to continue using it for a long time. But that doesn't make the stock price go up.
Classic case of a network call being slower than staying on the local computer (someone in Redmond should have known better)
