It's completely inconsistent with traditional Windows design language and there's no "Cancel" button or an X in the corner to click on so you can't cancel out of it with your mouse and have to reach for Esc on your keyboard
It also tries to funnel you into a shitty Microsoft service
That's because it's the Windows 8 design language and they didn't update it in a decade!
It's not the worst offender. There are older and worse screens that you see every day.
