If you don’t live on the Internet like I do, you might not know Sysinternals was “bought” by Microsoft (I’m not sure if it was actually bought or if Mark Russinovich just brought it along when he was hired by Microsoft). Now, you might know that, but did you know all those tools are offered in a single download now? Of particular note is ProcessMonitor which is a souped up version of Filemon/Regmon/ProcessExplorer. And if you don’t know what Sysinternals is, well, I can’t help you.
