If you haven’t heard of Process Explorer you have been hiding under a rock! It is very handy for looking at processes, who the process belongs to, and what DLLs are bound to those processes. Process Explorer can be a direct replacement for task manager, its especially handy with Windows XP as the task manager is quite minimal. Windows 7 borrows some of Process Explorers features, if you’ve bothered to compare the two. Below is an insert from Systinternals highlighting the updates.
This major update to Process Explorer adds a slew of enhancements and new functionality including network and disk monitoring, an improved multi-tab system information dialog, additional memory statistics, a new column that shows aggregate CPU usage for a tree of processes, improved DLL scanning performance and accuracy, command-lines in process tree tooltips, support for more than 64 CPU systems, and more.
