Just a few days ago we learned of Microsoft’s intention to implement a preloading technique to improve the fluidity of its operating system and, more specifically, the file explorer. Now, the specialized media Windows Latest has put this new feature to the test to see if the promise of a Fastest file explorer is fulfilled in reality or if it is simply an aesthetic patch.

The results of the technical tests have yielded interesting data. The feature, which keeps the browser loaded in the background, effectively improves boot times. According to the tests carried out, RAM memory consumption increases slightly: the process goes from taking up about 32 MB to almost 67 MB. Although it implies sacrifice system resourcesthe figure is negligible by current hardware standards, and the benefit in opening speed is notable, especially when the computer is under an intense workload.

However, the improvement has a clear limit. Although the browser window appears earlier, the user experience has not resolved all of its slowness problems. Testing indicates that critical elements such as the context menu are still slow to load, especially built-in options that are not native to the legacy system. This confirms that preloading is a startup aid, but not a comprehensive solution to software performance.

A modern design layer that hinders performance

The analysis of Windows Latest highlights an uncomfortable reality for users who migrated from the previous version: the browser Windows 10 is still faster and stable. The technical reason lies in the software architecture. While Windows 10 uses the classic Win32 interface, Windows 11 adds additional layers of modern design (WinUI and XAML) on top of that same old core. This mix of technologies forces the system to process more rendering elements, which generates that feeling of heaviness.

At the moment, this preloading functionality is in the testing phase within the versions Insider and is expected to reach all users early 2026. Although Microsoft has managed to make up for the initial wait times, the underlying code still needs deep optimization to match the immediacy offered by its predecessor. Without a doubt, it is these details that, along with other reasons, cause millions of PCs to remain stuck on Windows 10.
