Windows Phone's UI is still with us, from Windows 8 onwards. Everything on 8, 10, and 11 is optimized for a touch interface on a small screen, which is ridiculous on a modern desktop with a 32" or so monitor and a trackball or mouse.
From Windows 10, there is a switch between desktop and touch mode.
They stopped supporting small tablets some years ago though, and made it worse with every Windows update. I can only surmise that it was to make people stop using them. Slow GUI, low contrast, killed apps.
False. The Metro design was abandoned long ago. No live tiles, no typography-first minimal UIs in windows 10/11. I pin an email app to taskbar/start, I don't see the unread count.
