Runs `powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR SYSCOOLPOL 0` to set the system cooling policy to Active on AC power. Windows will ramp the fans to hold clock speed instead of throttling the CPU to stay cool — so sustained workloads keep their frequency. Desktops with adequate cooling benefit most. Reboot required so the active scheme re-reads it. Revert restores Passive cooling.
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.
