Windows 11 has received criticism for its stringent system requirements, confusing interface changes, and intrusive ads. A YouTube video by concept creator AR 4789 presents a mock-up of a fictional Windows 12.1, showcasing a sleek installation process that includes a mini-game. The design is modern and minimalist, focusing on a clean user experience, with a taskbar positioned at the top and a Start menu that retains a recommendations section. The concept features positive design elements, such as sleek highlights for thumbnail selections, and has garnered favorable feedback from viewers. There is an expectation that Microsoft may incorporate some of these design ideas into future operating systems.
