Sets SnapAssist = 0 so when you snap a window to one side, Windows stops popping up thumbnails of your other windows to fill the gap. Snapping itself still works. 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.
