Sets DefaultTTL = 64, the modern standard hop limit used by Linux/macOS (Windows defaults to 128). Mostly cosmetic/consistency; some networks treat the lower TTL more predictably. Reversible. Reboot recommended.
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.
