You know how your finger twitches to press ctrl shift esc whenever ANYTHING happens on your computer. And how its just oh so easy to kill a frozen program there. Well, theres a more ahem…advanced/expandable version of taskmanger, called System Explorer. This has detailed information about not just processes, but what explorer is doing, IE, drivers, connections, etc. Theres even a history of processes activities. One function that makes me like it nearly instantly is the registry/file snapshots, which lets you compare changes in your configuration. Of course, with this many functions, it ought to be purchased..but nope. Its free :)
Check out SystemExplorer.
