Sets TaskbarAnimations = 0 under Explorer\Advanced. Removes the slide/fade animations when taskbar buttons appear, combine, or the Start menu opens. The taskbar reacts instantly instead of playing a short animation on every interaction — a clear snappiness win, especially on lower-end GPUs. 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.
