If Task Manager Extension is Task Manager on steroids, then Mark Russinovich's Process Explorer is Task Manager in a ripped anabolic fury, fueled by high octane rage. In other words, it's extreme:
Definitely a SWEET tool, and I second Darrell’s thoughts. Another Great tool is “WhoLockMe” - Handy when you can’t figure out why a file is locked:
I’ve also been using it a couple years, still use task manager for most things, but sometimes you need more information for debugging and optimizing and process explorer is great for that. Although on one or two occasions (primarily when monitoring a process which then ends) the app sucks up 99% cpu and eventually I have to use task manager to kill it. Not sure why this happens and it has only happened a couple times so no real issue.
