How can I change the CPU clock speed of my computer? It is a Dell Inspiron 5720 laptop, running Windows 8.1 Pro. In Linux, I know there are ways of doing this from the operating system itself, instead of having to go through the BIOS, like this and this. Is this possible in Windows?

I've only seen it done with apps from the mobo vendor, but that doesn't mean it cant be done from commandline using some utility. – MDT Guy Nov 27 '13 at 15:23

I believe you can achieve lower frequencies from power options menu:

Setting maximum and minimum processor state to some percentage will probably fix the frequency on some level depending on your maximum CPU frequency.

However, this appears not to be under-clocking. A more detailed answer explains this in depth.
