Original Answer (See the section below for a more comprehensive solution.)
You have Windows Task Manager, which is built into Microsoft Windows itself.
From Wikipedia, the article Windows Task Manager (edit 19:04, 17 September 2012):
Windows Task Manager is a task manager application included with the Microsoft Windows NT family of operating systems that provides detailed information about computer performance and running applications, processes and CPU usage, commit charge and memory information, network activity and statistics, logged-in users, and system services. The Task Manager can also be used to set process priorities, processor affinity, forcibly terminate processes, and shut down, restart, hibernate or log off from Windows.
