Sets ShowCloudFilesInQuickAccess = 0 under Explorer\Advanced. Stops Explorer from pulling your OneDrive/Office 'recently used in the cloud' files into Quick Access. Keeps Explorer local and quiet — no cloud round-trip to populate the view, and your cloud activity isn't shown. Reversible.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
