Chameleon Task Manager

Chameleon Task Manager is an application similar to the Windows task manager that also lets you optimize your system performance by redistributing available resources to tasks with the highest priority.

The program offers a huge amount of information regarding each task: the program it belongs to, the resources consumed by each process, system performance, open files, and registry elements in use.

When opening the program for the first time, you'll be asked if you want to use the program's optimizer to assign resources to active tasks according to their usage.

If you're worried about your system performance and want reliable information regarding the tasks it's performing, Chameleon Task Manager is a really good option.
