Companion to the no-acceleration tweak above. Sets the lower threshold of the XP-era acceleration curve to 0. Harmless if MouseSpeed is already 0; some games still respect these legacy thresholds.
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.
