Sets ListviewShadow = 0 under Explorer\Advanced. Turns off the drop-shadow rendered behind desktop icon text. One of the standard 'Adjust for best performance' visual effects — pure GPU compositing overhead with no functional value. 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.
