Tested: Windows 11’s ‘faster’ File Explorer (preloaded) is still slower than Windows 10, and uses additional RAM.
Microsoft is testing a “fix” to Windows 11’s File Explorer, which is supposed to improve its launch performance by preloading it in the background.
The move came after years of user complaints about the slow File Explorer, especially after coming from the now-retired Windows 10 File Explorer, which was snappier every time you launch it. But Microsoft’s solution to preload the File Explorer instead of fixing the underlying code is being scoffed at by users online.

Windows 11 now preloads File Explorer to speed up launch times, but our tests show the fix only goes so far to speed-up the launch.
