Points all active network adapters at Cloudflare's 1.1.1.1 / 1.0.0.1 resolvers — one of the fastest public resolvers, with a strong no-logging privacy stance. One-shot: to go back to your router/ISP DNS, run 'Reset DNS to automatic'.
MaxTweaks applies this tweak with one click and clearly marks it as a one-shot action so you always know what can and can’t be undone. A System Restore point is offered before batch changes, and every tweak links to its official source.
