I haven't fully tested it, but Process Tamer looks promising on first blush. It senses processes that hog CPU cycles and "tames" them by forcing them to free up CPU cycles for other processes. This often makes your computer feel more responsive when processor intensive apps slow things to a crawl or even lock up the computer temporarily. Of course those processes are slowed by being forced to free CPU cycles, so it can be a mixed bag. I've found it to be stable and of apparent benefit. That's pretty good praise considering I'm using the Windows 7 beta. Says a lot good about Windows 7, too.
You no longer have to be an involuntary beta tester. Dr Dave guides you through the technology maze, separating the hype from technology that actually adds to the quality of your life.
