Microsoft is enhancing File Explorer for Windows 11 Insider program users, focusing on improved launch speed and performance. A preloading feature was tested that allows File Explorer to load in the background for faster access, which users can disable in the Folder Options. These updates follow the introduction of Startup Boost for Office applications, which also aims to improve loading times. The Windows Insider Program Team is also working on enhancing the reliability of the explorer.exe process and addressing issues with bright white flashes when opening File Explorer in dark mode. Additionally, a new Xbox mode has been introduced for Windows 11 PCs, providing a full-screen gaming interface to reduce distractions. These updates are being rolled out to Insiders in the Release Preview channel with specific Windows 11 builds installed.
