Microsoft’s Windows 11 users have encountered a performance slowdown in File Explorer following the introduction of a preloading feature intended to speed up the application. Instead of improving launch times, the feature has caused increased RAM usage, which particularly affects older PCs. The issue has frustrated many users as File Explorer now opens slower than expected, especially when loading its Home screen with cloud-integrated content from OneDrive and Microsoft 365.
The slowdown is most evident on the default Home landing page, which displays recent files, favorites, and recommended content pulled from cloud services. Each time File Explorer launches, it must query OneDrive and Microsoft 365, synchronize cloud content, and populate these sections. Users with folders synced to OneDrive or SharePoint experience additional delays due to the integration, leading to visible loading messages before any files or folders appear. This behavior contrasts with Windows 10, where File Explorer often opened more quickly, primarily because it did not perform extensive cloud queries on launch.
A practical solution to mitigate this slowdown involves changing the default launch screen in File Explorer from Home to This PC. By doing so, users access local drives directly, avoiding automatic cloud queries and online content syncing. The adjustment can be made by opening File Explorer, selecting the ellipses menu, clicking Options, and updating the “Open File Explorer to” setting under the General tab. This simple tweak reduces unnecessary background processes while retaining core functionality, resulting in noticeably faster startup times.
Despite the preloading feature still being active, it can complement the This PC setting by loading File Explorer’s core components into memory before the user opens the application. This combination delivers a performance improvement reminiscent of previous Windows 10 experiences. However, preloading alone provides only minor gains while increasing memory usage, as File Explorer in Windows 11 relies on a modern WinUI interface layered on its legacy Win32 core. The app must initialize interface elements, load shell extensions, sync cloud icons, and communicate with online services each time it starts, which contributes to slower launch times.
Microsoft has been working to optimize performance in recent updates. Improvements include faster loading for the Home tab, quicker archive extraction, and reduced delays when opening folders with large media libraries. While preloading aims to reduce initial startup delays, users on older hardware or heavily integrated cloud setups are advised to pair it with the This PC launch setting for smoother performance. These adjustments highlight the balance between modern interface features and system efficiency in Windows 11, offering practical ways to regain speed without disabling core enhancements.
