Microsoft has rolled out the Windows 11 KB5089573 update, which brings quality of life and foundational OS improvements to make PCs feel faster and more responsive. The update is the first under Microsoft's Windows K2 effort, focusing on addressing top criticisms and delivering foundational improvements. It includes general OS performance improvements, accelerating app launch and core shell experiences, and improves Windows reliability on sign-in and lock screens, File Explorer, and touch gestures. The update also features Low Latency Profile improvements, which can result in system flyouts appearing up to 70% faster and app launches up to 40% faster. The update is now generally available as an optional OS update. Microsoft has been testing these changes with Insiders, and testers have noted genuine performance gains. The performance improvements will be enabled over the coming weeks as Microsoft makes it available in more waves, making Windows 11 feel more snappy and responsive to input, with a noticeable difference in system performance.
