Microsoft is enhancing the performance of File Explorer in Windows 11, moving beyond the initial preloading feature introduced last year. Tali Roth, Microsoft's Head of Product for Windows Shell, stated that the company is committed to implementing targeted optimizations to improve the speed and responsiveness of File Explorer. The preloading adjustment improved the app's launch time but did not resolve performance issues during subsequent uses, as users reported sluggishness when navigating folders. Microsoft's new strategy involves deeper foundational engineering to reduce unnecessary disk reads and application hangs. The ongoing "fix Windows 11" campaign indicates progress, though questions remain about the initial performance issues.
