One thing I do NOT like about Windows 7 is the reach through to the BIOS CPU power management settings that it has. My preference on a DESKTOP system, is to have the CPU running at full power and not for it to be throttled by constant changes of the voltage. There is no way to avoid this with Windows 7 as it by default sets CPU power management to mess with both the fan speed and the CPU throttling and there is no way to avoid that.
These are the only two available options and they both suck and are nonsensical in my opinion:
If you change the power options to high performance then CPU min/max is set to %100.
