Sets dmwappushservice (Device Management Wireless Application Protocol Push message Routing Service) to Disabled and stops it now. Its nominal job is routing device-management (MDM) push messages, but it is also a known secondary telemetry transport and is routinely disabled alongside DiagTrack. If your PC isn't enrolled in a corporate MDM you don't need it. No-op if the service isn't present on your build. Fully reversible (revert restores the original start type).
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.
