Windows 11 Revamps File Explorer with Faster Load Times

Windows 11 has introduced a new feature in its preview build aimed at reducing the slow initial loading times of File Explorer. By preloading File Explorer when a PC boots, Microsoft has managed to cut opening times from approximately two seconds to one second in various tests.

Performance Gains and Memory Use

This improvement in speed does come with increased memory usage: File Explorer now uses about 67 MB of RAM instead of the previous 32 MB, reflecting an increase of 35 MB. While some regard this RAM trade-off as minor, it delivers a noticeable improvement in responsiveness.

Broader Implications for Windows 11

Though the change specifically targets initial load times, critics argue it highlights a pattern where Microsoft opts for preloading as a solution rather than implementing thorough performance enhancements. This could raise concerns as more apps adopt similar preloading tactics, potentially leading to accumulative memory usage increases.

The fix is seen as a temporary 'fudge' compared to implementing a fully optimized File Explorer, prompting questions about why the sluggishness existed initially.
