Windows – Lightweight CPU usage monitor?

I’m looking for a lightweight CPU usage monitor, something that can sit in a corner of my screen telling me how much of my CPU is getting used. Anyone know of one?

Solution:

Moo0 SystemMonitor lets you keep your eye on system resource usages of your PC. It currently supports 34 kinds of information including CPU, memory, network, and detailed hard disk drive usages. Using this software, you may discover what is limiting your system performance in each occasion.

Available as installer or portable, and pretty lightweight too – it’s using only 7 MB RAM.
