Software> CPU Pegged Monitor
Sometimes your computer become unresponsive, and the only way to continue without a dreaded reboot is by using the Task Manager. But sometimes your computer can't even launch that. This tool automatically launches the Task Manager when the CPU hits a configurable threshold for a certain amount of time, by default over 90% for 15 seconds.
Requirements: Windows XP or higher with Microsoft .Net installed.
