If you’re done with Task Manager then check out SystemExplorer at http://systemexplorer.mistergroup.org. SystemExplorer is a free utility that will help you search through those processes for the ones that are virus laden, leaking memory or just plain not supposed to be there and therefore wasting your valuable system resources.
SystemExplorer can show file paths, parent processes, process publishers, action histories and let you search for details against a database. In short, there have been great replacements for Windows’ Task Manager for years but this one might just be one of the better ones we’ve tried.
