Windows 11 is finally starting to see the changes Microsoft has promised for months, except the best parts are still limited to Windows Insiders and mockups. I appreciate Microsoft's efforts to revamp Windows 11 — better late than never — but some of these improvements should have shipped years ago. The status of Windows 11 makes me ask why Microsoft didn't aggressively start climbing the metaphorical mountain years ago. Microsoft is updating several core parts of Windows 11 with WinUI, which improves performance and even helps Windows 11 run on PCs with less RAM. Microsoft's CVP of Design and Research on Windows, Marcus Ash, joined the most recent Windows Central Podcast and discussed the challenges of updating Windows.
