Overview: In this episode of Defrag Tools, Andrew and I walk you through Sysinternals Process Explorer. Process Explorer is a comprehensive replacement for Task Manager. It allows you to view the details of the processes running on the computer, both at a point in time and historically. The performance graphs allow you to view the CPU, I/O, Memory and GPU usage. Process Explorer can be used to find file locks, loaded DLLs, autostart locations, and many more things.
