Add a gadget which shows your CPU's statistics on desktop.
Windows 8 CPU Meter is a gadget which provides a Windows 7 like CPU meter gadget on PC. You can move the Windows 8 CPU Monitor freely around your desktop or set it to always appear above Windows by right-clicking it and enabling the 'Always on top' option in its context menu. This is quite useful when you're running a high performance program and want to keep a constant eye on how your computer's taking the pressure.
An added feature allows you to know the status of your hard drive if you want.
Cons
Comparatively to Win 7, you cant change the opacity. its not really a con... but it is the only difference i can find. Also, i think you need to keep the downloaded file somewhere on your hard drive for it to work.
Summary
Overall, works just like the old one. Hasn't given me any trouble.
