If Windows wants faster apps, then remove the relentless advertising and web hooks for OneDrive in Photos - especially when OneDrive has been uninstalled, Remove web search from the start Menu, and speed up the animation delay 10x. Windows would instantly feel better.
While they're at it they can remove the clipped/rounded corners from windows, return the "Uninstall or change a program" button to My Computer, and make Photos Legacy correctly display the right thumbnails instead of the generic "blank file" icon.
Then after that they could let people move the task bar, and move the power options to the left side of the start menu where it's way easier to access, make the start menu way more customizable (or at least have a classic mode), put links to documents/photos/videos/downloads in places that are actually convenient, redesign the entire Microsoft store from the ground up, label their crappy low-contrast icons, show the entire right click menu by default, increase information density in their menus by 3x... and also don't have Windows completely break and force me to do a clean install after I spent literally the last 2 weeks in the registry trying to get this horrible, backwards, unintuitive, anti-user, and unstable GUI anywhere on the same planet as usable.
Do these few simple things, and Windows 11 Microsoft might one day be able to convince up to 35% of their users to take this free "upgrade" before this awful product gets replaced by something even worse.
