More System Utilities than you can Shake a Stick At

http://www.sysinternals.com/

I don't know HOW these guys aren't a common household name. Think of any cool system utility for Windows that you wished that you had at some point. Guess what? Yup. These guys wished the same thing, so they made them. Most of them are 100% free, too. Most of what they charge for is NTFS conversion stuff and recovery stuff.. Things you probably either already have or don't need.

Honestly, these guys reference their software to MICROSOFT KB articles, where MS recommends their software. I have no clue why they're not a Fortune 500 company yet. Anyway, here's a list of some of their more interesting software. Well anyway, the stuff I found interesting. :)

Diskmon v2.01
This utility captures all hard disk activity or acts like a software disk activity light in your system tray.

The read-only version is freeware.
