Sets AJRouter (AllJoyn Router Service) to Disabled. AllJoyn is a legacy IoT/smart-home device-interop framework almost nothing on a normal desktop uses. Disabling frees the service. Only relevant if you use AllJoyn-based IoT gadgets that talk to your PC. 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.
