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.

Windows 11 Can Update Apps Even If the Microsoft Store App Is Removed

Microsoft is testing a new feature in Windows 11 that allows users to update applications installed via the Microsoft Store even if the Store app is uninstalled. This feature can be accessed through Settings > Apps under a new "App Updates" option, enabling users to check for updates independently of the Store. Each application likely has an API for connecting to Microsoft's server for update checks. Currently, the "Check for updates" button does not function as intended. Additionally, Microsoft has improved the uninstallation process for Store apps, allowing users to remove them directly through the Store interface instead of the "Add or remove programs" section. This enhancement was introduced with Windows 11 Insider Preview Build 26220.7271 (KB5070307).

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.

Windows 11 gets new Cloud Rebuild, Point-in-Time Restore tools

Microsoft introduced two recovery features for Windows 11 at the Ignite developer conference: Cloud Rebuild and Point-in-Time Restore (PITR). PITR allows users to revert a Windows 11 system to a previous stable state in minutes by capturing comprehensive snapshots of the system, restoring the operating system, settings, and files. This feature will enter preview with an upcoming Windows 11 Insider preview build. Cloud Rebuild enables complete reinstallation of Windows 11 from the cloud for devices with persistent issues, using the Intune portal for selection of the Windows release and language. It employs Autopilot for zero-touch provisioning and streamlines user data restoration through OneDrive and Windows Backup for Organizations, reducing downtime significantly. Both features will be integrated into Microsoft Intune in the first half of 2026, allowing remote recovery actions and management of Windows Recovery Environment functionalities. Additionally, Microsoft is testing an updated version of Quick Machine Recovery (QMR), which helps resolve Windows boot failures without physical access. QMR engages the Windows Recovery Environment during boot failures, analyzes crash data, and allows Microsoft to implement remote fixes. The latest version improves the boot-repair process by conducting a single scan to resolve issues.

Windows 11 26H1 Focuses on New Silicon Support, Not New Features

Microsoft has released Windows 11 Insider Preview Build 28000, focusing on hardware optimization rather than major user interface changes. This build supports advanced silicon from Qualcomm and NVIDIA, specifically targeting Windows-on-Arm platforms featuring Snapdragon X2 Elite processors and NVIDIA's N1 and N1x SoCs. The 26H1 update will not be a feature update for version 25H2 but will include platform modifications for new hardware, with no action required from users. Microsoft plans to use an enablement package (eKB) to unlock functionalities within the 26H1 framework, similar to the 25H2 update, which also introduced few new features and emphasized security improvements while deprecating certain features like PowerShell 2.0 and WMIC due to security vulnerabilities. Additionally, IT administrators can remove pre-installed Microsoft default applications on Enterprise and EDU devices through Group Policy or MDM CSP.
