This tool (built into XP, Vista, and Win7) lets you see, in real time and in collected data logs, how your PC reacts as different programs run — or fail to run!
In Part 1 of “Exploring Windows’ Administrative Tools” (May 10 Top Story), you saw how a few easy tweaks can give you two-click access to hundreds of Windows’ most powerful diagnostic, tuning, and administrative features.
