Runs `netsh interface teredo set state disabled`. Teredo tunnels IPv6 over IPv4 NAT; on most home networks it adds latency, occasional connection churn, and an attack surface without benefit. Disabling can improve some games' NAT behaviour (though a few P2P features rely on it). Revert restores the default Teredo state.
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.
