BITS is used by Windows Update and Microsoft Store for throttled background downloads. Setting to Manual lets Windows start it when needed but stops it from idling. Don't disable outright — Windows Update will silently fail.
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.
