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 is testing a Windows 11 tweak that preloads File Explorer in the background to make it faster

Microsoft is introducing a feature in Windows 11 that preloads File Explorer in the background to improve its launch performance. This change aims to reduce the delay users experience when opening File Explorer from a cold start, allowing the interface to load almost instantaneously. Windows president Pavan Davuluri acknowledged user feedback regarding performance and confirmed that enhancements are being made to the platform beyond recent AI advancements.
