These updates mark one of the most substantial visual and functional overhauls since Windows 11's initial release, signaling Microsoft's commitment to refining the user experience.

A Fresh Start Menu Design

The most noticeable change in these builds is the completely redesigned Start Menu, which now features a cleaner, more modern layout. Microsoft has streamlined the interface, reducing clutter while improving accessibility. Key changes include:
