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.
