The Windows Task Manager is often used for troubleshooting – perhaps closing an application that isn’t working properly or monitoring system resource usage. However, there’s a lot more you can do with Windows 7’s Task Manager.
To quickly open the Task Manager, right-click your taskbar and select Start Task Manager. You can also press Ctrl+Shift+Esc to quickly launch the Task Manager with a keyboard shortcut. Windows 8 may have a great new task manager, but Windows 7’s is still useful.
