Does anyone know of any good free alternatives to the standard Windows Task Manager besides the Resource Monitor? I'm looking for a lightweight program that displays detailed info about my CPU, RAM, Hard Drive, processes, services, and etc.

Sysinternals Process Explorer is a good Task Manager replacement, but it's more for, well, processes/services than for system info. It's lightweight; no install needed, just unpack.

    It also has the option to 'Replace Task Manager' so that when you invoke TaskMgr, you get ProcExp instead. – JBRWilkinson Jan 30 '10 at 21:38
  • Yeah! Use it! It is he best! – kokbira Jul 15 '10 at 3:25
  • Process Explorer is not lightweight, it take some seconds to load especially when there is application taking up the CPU resource. I need a lightweight yet powerful task manager, unfortunately ProcessExplorer is not one I'm looking for. – null Dec 18 '14 at 17:43

A great alternative to Process Explorer is Process Hacker. It's also free but this one is open-source. Same informations, some more features.
