Task Manager

Use task manager to monitor processes and performance of your system

Start Task Manager:

• Ctrl+Shift+Esc
• Right-click the taskbar and select 'Start Task Manager'
• Ctrl+Alt+Del and select 'Start Task Manager'

Task manager now has six tabs:

Applications

Lists running programs that have corresponding task bar buttons and their current status. 'Applications' lists programs that are running in a foreground window, and generally represent programs that have been explicitly launched by a logged-on user.

A status of 'Not Responding' does not necessarily mean that the program has died: it could simply be too busy to communicate its status to task manager.

Right-click in the applications pane to start a new task, or simply click the 'New Task...' button. Right-click an application to expose a context menu that allow you to:

End the application

has the same effect as closing the application
