A new concept video titled 'Windows 12.2' has been created by YouTuber 'AR 4789', showcasing a refined vision for Microsoft's operating system. The video features a clean interface inspired by Apple's Liquid Glass and includes elements like the Aero transparency effect from Windows Vista. It presents nostalgic features such as a Windows 7 theme and various customizable taskbar options. However, the likelihood of Microsoft adopting these ideas is uncertain, especially given the mixed reception of Windows 11. Observers suggest that any future iteration will need to represent significant advancements rather than incremental updates. Microsoft may focus on maintaining Windows 11 with annual updates while investing in a more AI-centric operating system.
