How does windows "limit" the CPU (Power Options / Battery saving)
Yes Windows limits the CPU speed. Using ACPI frequency, multipliers and voltage can be changed ''actively'' (i.e. when required without needing to manually change in the BIOS). With your above settings watch the frequency actively change in Resource Monitor (rather than just in Task Manager (which only show''s the usage of the current processor speed, not the speed).
