It’s all part of Microsoft’s effort to modernize Windows.
Microsoft has started detailing some of the design approaches it has used for Windows 11 and its attention to detail for daily micro-interactions. That includes things like a checkbox that has an animated tick to subtly let you know when you interact with it, or a settings cog that spins when you hover over it. Plenty of buttons in Windows 11 pop with faint signs of life or bounce as you move around the OS.
