Windows performance counter

Sometime I need to check perfmon in Windows to see various statistics data. This time I put the reference link down here. Anybody know a updated version for 2003 or Vista?

Update: although I could not find performance counter guide for Windows 2003, but this tuning guideline is nice. And this performance advisor should be useful for Windows administrators, I guess.
