Disables Microsoft\Windows\Maintenance\WinSAT, the Windows System Assessment Tool that periodically re-measures your performance index. Disabling stops the occasional background CPU/disk burst it causes; your existing performance index is kept.
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.
