CPU not stepping

In Windows you can experience that your CPU isnt stepping down the frequency when idle in Windows. That typically occour when power options are choosen to be "Performance". If you want it to step down the clocks, go to power options, find the plan it use, click change plan, click advanced power settings, find processor power management, click minimum processor state and in "Setting" adjust it from 100% to 5%. Click Ok and it will start stepping again.
