Windows 11’s “fast” File Explorer is slower than ever and hogs more RAM

Microsoft has introduced a background-preloading update for File Explorer in Windows 11 Insider builds to enhance application speed and smoothness. Initial tests indicate that the preloaded version opens more slowly than the standard Explorer in Windows 10, particularly on devices with limited RAM (4-8 GB), leading to sluggish performance during multitasking. Users have reported slower context menus and folder navigation, despite the intended improvements. Preloading is enabled by default in the Insider build, but Microsoft has not confirmed plans for a broader rollout. The update raises concerns about the efficiency of Windows 11's design, as the combination of older Win32 components with newer WinUI elements may compromise core performance. Users relying on File Explorer may experience delays and unresponsiveness, particularly if their systems have limited resources. Microsoft may reconsider its approach to the preloading feature in future Insider builds, and users experiencing slowdowns might consider disabling it or reducing visual effects to improve performance.

Hooray, Microsoft is making File Explorer faster, but it’s still slower than Windows 10 and consumes more RAM. Boo

Microsoft is testing a preloading feature for File Explorer in Insider Preview Build 26220.7271, available on the Dev and Beta channels. Feedback on this new functionality has been mixed, indicating that while improvements are being made, they have not yet met user expectations. Further refinements are needed for Windows 11, with hopes that the preloading feature will enhance performance when it officially launches in the regular Windows Update scheduled for 2026.

Complaints about Windows 11’s fix for File Explorer sluggishness are overblown – but they underline a fundamental problem with the OS

Windows 11 has introduced a fix in a preview build to improve the speed of File Explorer by preloading the application during system boot. Initial tests indicate a noticeable speed improvement, although it doubles RAM usage with only a modest increase in performance. Critics argue that Microsoft's approach appears reactive and lacks a comprehensive strategy for overall performance enhancement. The preloading fix does provide a tangible speed boost with manageable RAM impact, but concerns remain about the broader user experience and future updates.

Windows 11’s new pre-loaded File Explorer is reportedly still slower than Windows 10

Microsoft has acknowledged the sluggish performance of Windows 11's File Explorer and is introducing a preloading feature to enhance its speed. Initial tests show that the preloaded version opens faster than the non-preloaded version, using approximately 30MB of additional RAM. However, Windows 10's File Explorer outperforms the preloaded version of Windows 11 in both opening and closing speeds. This performance gap may hinder the adoption of Windows 11, as many PCs compatible with the new OS remain on Windows 10. Further enhancements are necessary for Windows 11's File Explorer to match or exceed the responsiveness of Windows 10.

Preloading File Explorer in Windows 11 Doubles RAM Usage, Offers Minimal Speed Boost

Microsoft has initiated background preloading of File Explorer to improve accessibility, but this has led to increased RAM usage without significant performance gains. Testing shows that the standard launch of File Explorer uses approximately 35 MB of RAM, while the preloaded version consumes about 67.4 MB due to additional background processes. Despite preloading, File Explorer remains sluggish, with no substantial enhancements in functionality or user experience. Visual tweaks may create an illusion of faster launches, but core performance issues persist, exacerbated by the transition to Windows 11's modern UI elements.

Tested: Windows 11’s ‘faster’ File Explorer (preloaded) is still slower than Windows 10, and uses additional RAM

Microsoft is testing a new feature for Windows 11's File Explorer that involves preloading the application in the background to improve performance. This preloading aims to address user complaints about File Explorer's sluggishness compared to Windows 10. Preloading involves pre-caching necessary data to facilitate quicker launches. Testing showed that RAM usage increased slightly from 32.4MB to 35MB with preloading enabled, resulting in a total of 67.4MB during background preloading. While there was a slight improvement in launch times, it was not significant without close examination. Under full load conditions, preloading demonstrated clearer advantages in launch speed. However, the overall sluggishness of File Explorer, particularly with context menu interactions, remains an issue. Users can optimize their experience by disabling transparency and animation effects and changing default folder settings. The performance disparity between Windows 10 and Windows 11 File Explorers is attributed to additional rendering layers in Windows 11. The preloading feature is available for testing in the Windows 11 Insider Preview Build 26220.7271 (KB5070307), with a broader rollout expected in early 2026.

Microsoft preloads File Explorer to mask performance issues

Microsoft is addressing sluggish launch times for File Explorer by preloading the application in the background, rather than streamlining its code or removing features. This update is available in a Windows Insider build for the Dev and Beta Channels. The preloading feature is experimental and can be disabled by users in the Folder Options under the View tab in File Explorer. Microsoft previously open-sourced the classic Windows File Manager in 2018, which was a lightweight tool for file system activities. Over time, File Explorer has increased in size and complexity, leading to performance challenges.

Microsoft Is Finally Doing Something About Windows 11’s Slow File Explorer

Microsoft is testing a preloading feature for File Explorer in Windows 11, aimed at enhancing its performance by loading it in the background before user interaction. This feature is currently available in Windows 11 Insider Preview Build 26220.7271 for the Dev and Beta channels. Users can enable it through File Explorer settings, but its public rollout is uncertain as Microsoft is still exploring its viability. Additionally, a known bug allows users to temporarily boost File Explorer's performance by double-tapping Control + F11, though this may disrupt other system functionalities.

Microsoft is speeding up and decluttering File Explorer in Windows 11

Microsoft is enhancing the File Explorer in Windows 11 with a preloading feature to improve startup speed, particularly on less powerful hardware like handhelds and tablets. Users will have the option to disable this feature if they prefer not to run File Explorer in the background. Additionally, the context menu is being refined to declutter the interface by moving less frequently used actions into submenus and introducing a new manage file flyout that consolidates various functions. Cloud file options will also be organized into a dedicated flyout. These updates are currently in testing in the latest Dev preview builds, with a broader rollout expected in early 2026.

Microsoft says it’s fixing a baffling way in which Windows 11 is much slower than Windows 10 – and it’s about time

Microsoft has released a new preview build of Windows 11 (build 26220.7271) in the Dev and Beta channels, focusing on improving File Explorer performance and the right-click menu. Key features include: - A preloading feature for File Explorer that allows it to load in the background during Windows 11 startup, reducing sluggishness when accessing folders for the first time. - A streamlined right-click menu in File Explorer, condensing options and relocating actions like 'Compress to ZIP' and 'Set as Desktop Background' to a new 'Manage file' flyout for better organization. Additionally, Microsoft is testing the Xbox Full Screen Experience for Windows 11 PCs, indicating potential future gaming feature integration. Users can opt to disable the preloading feature if desired.
