Microsoft has released the optional KB5044384 preview cumulative update for Windows 11 24H2, which includes twenty-four changes, including a bug that caused the sfc /scannow command to always display corrupt file errors.

The October 2024 non-security preview update is designed for power users and IT admins to test upcoming changes to the operating system before next month's November Patch Tuesday.
