Sets EnableBalloonTips = 0 under Explorer\Advanced. Suppresses the legacy balloon/tooltip nags that pop from the notification area ('Click here to finish setting up', driver hints, feature ads). Real toast notifications from apps are unaffected — this only kills the old shell balloon tips. Takes effect on the next Explorer refresh. 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.
