Mail and Taskmanager

 Task Manager has two views. The first time Task Manager is invoked by a user, it shows in a simplified summary mode (described in the user experience as Fewer Details). It can be switched to a more detailed mode by clicking More Details. This setting is remembered for that user on that machine.[3]

Summary mode[edit]

In summary mode, Task Manager shows a list of currently running programs that have a main window. It has a "more details" hyperlink that activates a full-fledged Task and mailManager with several tabs.

Right-clicking any of the applications in the list allows switching to that application or ending the application's task. Issuing an end task causes a request for graceful exit to be sent to the application.

Processes and details[edit]

The Processes tab shows a list of all running processes on the system. This list includes Windows Services and processes from other accounts. The Delete key can also be used to terminate processes on the Processes tab. By default the processes tab shows the user account the process is running under, the amount of CPU, and the amount of memory the process is currently consuming. There are more columns that can be shown. The Processes tab divides the process into three categories:

Apps: Programs with a main window

Windows processes: Components of Windows itself that do not have a main windows, including services

Background process: Programs that do not have a main window, including services, and are not part of the Windows itself

This tab shows the name of every main window and every service associated with each process. Both a graceful exit command and a termination command can be sent from this tab, depending on whether the command is sent to the process or its window.

The Details tab is a more basic version of the Processes tab, and acts similar to the Processes tab in Windows 7 and earlier. It has a more rudimentary user experience and can perform some additional actions. Right-clicking a process in the list allows changing the priority the process has, setting processor affinity (setting which CPU(s) the process can execute on), and allows the process to be ended. Choosing to End Process causes Windows to immediately kill the process. Choosing to "End Process Tree" causes Windows to immediately kill the process, as well as all processes directly or indirectly started by that process. Unlike choosing End Task from the Applications tab, when choosing to End Process the program is not given warning nor a chance to clean up before ending. However, when a process that is running under a security context different from the one of the process which issued the call to TerminateProcess, the use of the KILL command line utility is required.[4]

Performance[edit]

The Performance tab shows overall statistics about the system's performance, most notably the overall amount of CPU usage and how much memory is being used. A chart of recent usage for both of these values is shown. Details about specific areas of memory are also shown.

There is an option to break the CPU usage graph into two sections: kernel mode time and user mode time. Many device drivers, and core parts of the operating system run in kernel mode, whereas user applications run in user mode. This option can be turned on by choosing Show kernel times from the View menu. When this option is turned on the CPU usage graph will show a green and a red area. The red area is the amount of time spent in kernel mode, and the green area shows the amount of time spent in user mode.

The Performance tab also shows statistics relating to each of the network adapters present in the computer. By default the adapter name, percentage of network utilization, link speed and state of the network adapter are shown, along with a chart of recent activity.
