Sets SilentInstalledAppsEnabled = 0 under Content Delivery Manager. Stops Windows from silently downloading and installing 'suggested' apps and promoted titles (the ones that appear in Start unprompted). Per-user. Safe and 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.
