Taskbar Meters is a handy utility which runs on Windows 7 Taskbar allowing you to track windows performance based on Memory, Disk and CPU usage. The Icon colour changes from Green to Red based on configuration and you can track which applications are consuming too much of resources on Windows 7 machine.
The only drawback is you will have to run three utilities but with the Jumplist you can launch any of the other two utilities one by one.
