Advanced Diagnostic Tools in Windows 7

Windows Task Manager

If you’ve used Windows before, you’re probably familiar with Windows Task Manager. One of the fastest ways to access Windows Task Manager is by right-clicking the Windows taskbar and selecting Start Task Manager.

The information you find in Windows Task Manager is less detailed than what you see in Resource Manager but can provide information that is not shown in Performance Monitor, including what services are currently running and what users are logged in to the computer.
