Sets Start_NotifyNewApps = 0 under Explorer\Advanced. Turns off the orange 'New' highlight Windows paints on freshly installed apps in the Start menu. Pure visual nag — the apps are still there and searchable. 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.
