Sets the Chrome policy BackgroundModeEnabled = 0 so Chrome doesn't keep a process alive after you close all windows. Frees RAM/CPU at idle. Reversible.
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.
