Task Manager (Windows) - Wikipedia. Task Manager, previously known as Windows Task Manager, is a task manager, system monitor, and startup manager included with Microsoft Windows systems. It provides limited 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. Windows Task Manager was introduced with Windows NT 4. Previous versions of Windows NT included the Task List application, which had far fewer features. The task list was capable of listing currently running processes and killing them, or creating a new process.

In Windows XP only, a Shutdown menu is also present that allows access to Standby, Hibernate, Turn off, Restart, Log Off, and Switch User. Windows 3. x and Windows 9x had a program known as tasks to display the programs currently running. This file was executed by running the taskman.

Windows folder. A set of rules. Most applications that have a taskbar entry will appear on this tab, but this is not always the case. This is different from what happens when End Process is chosen from the Processes tab.

Processes. This list includes Windows Services and processes from other accounts. Prior to Windows XP, process names longer than 1. Choosing to End Process causes Windows to immediately kill the process. Choosing to . 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 Terminate. Process, the use of the KILL command line utility is required.

There are many more columns that can be shown by choosing Select columns.. 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.

Serial Line Internet Protocol slip 1 (sl. To move smoothly, easily, and quietly: slipped into bed. Do you want your Computer to a Server and want to prevent it from Shutting Down? Or Do do you want to prevent anyone from Shutting Down your PC for various reasons? User Account Control (UAC) is a new security feature in Windows Vista that requires all users to log on and run in standard user privileges mode instead of as.

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. Networking. 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. More options can be shown by choosing Select columns.. On server computers, there may be several users connected to the computer using Terminal Services. As of Windows XP, there may also be multiple users logged onto the computer at one time using the Fast User Switching feature. Users can be disconnected or logged off from this tab.

Update interval. Once changed in Windows XP, the default update rate of 1 s can only be reset by editing the Registry binary data in HKEY. The interval is stored in milliseconds at offset 0. Not all windows are shown in this view. For example, modal dialogs (windows for which there is not a separate thread) do not appear. This is why many dialogs and error messages are not shown.

The term Task used in the first column can be confusing, as there is no inherent concept of Tasks on Windows Operating System, except those configured in the Task Scheduler to run periodically. The Status column shows the status of the thread that owns a window, in terms of windows message processing. When the status of an application appears as Running this indicates that the thread is responsive to windows messages. When the status appears as Not Responding it means that the thread is not, at the moment, responsive to windowing messages.

It could be waiting (sometimes referred to as . A process consuming 0. CPU will be reported as 0. Task Manager. The System Idle Process is the first process that is created when Windows is loaded, and it always has a process ID of 0. There is one thread in the System Idle Process for each CPU in the system. When the CPU has no other work to do, the Windows scheduler selects the CPU's corresponding idle thread for execution. The accumulated CPU time of this process therefore shows the total CPU time that has not been used.

In early versions of Windows NT the idle threads were short idle loops consisting primarily of a . Up to thirty different columns (depending on the version of Windows) can be selected for display including various memory and I/O options and the number of handles and threads in use. Performance tab. Mapped files such as DLLs used by multiple processes are instantiated one single time in physical memory, and then shared across all referring processes.

As memory consumption is accounted individually for each process, the total of all process working sets will commonly be larger than the actual total memory being used. Task Manager has an alternate interface without any menu options or tabs. This is called the Tiny Footprint mode. Double- clicking on any empty space besides the data and/or menus changes Task Manager into this mode; double- clicking in the border switches it back.

In some versions of Windows, the keyboard shortcuts. Ctrl+Tab . Tiny Footprint mode does not show the memory usage graph if the tab selected is Performance. History. Also, in Windows 9x, there is a program called Tasks (TASKMAN. EXE) located in the Windows directory. TASKMAN. EXE is rudimentary and has fewer features. The System Monitor utility in Windows 9x contains process and network monitoring functionality similar to that of the Windows Task Manager. These show the full name and path of the executable image running in a process, any command line parameters that were provided, and the image file's .

Virtualization status refers to UAC virtualization, under which file and registry references to certain system locations will be silently redirected to user- specific areas. By right- clicking on any process, it is possible to directly open the Properties of the process's executable image file or of the directory (folder) containing the process. The Task Manager has also been made less vulnerable to attack from remote sources or viruses as it must be operating under administrative rights to carry out certain tasks, such as logging off other connected users or sending messages. The user must go into the .

Showing processes from all users requires all users including administrators to accept a UAC prompt, unless UAC is disabled. If the user is not an administrator, they must enter a password for an administrator account when prompted to proceed, unless UAC is disabled, in which case the elevation does not occur. By right- clicking on any running process, it is possible to create a dump. This feature can be useful if an application or a process is not responding, so that the dump file can be opened in a debugger to get more information. The Shutdown menu containing Standby, Hibernate, Turn off, Restart, Log Off and Switch User has been removed.

The Performance tab shows the system uptime. Windows 8. This view only shows applications and their associated processes. Resource utilization in the Processes tab is shown with various shades of yellow, with darker color representing heavier use. The Performance tab is split into CPU, memory, disk, ethernet, and wireless network (if applicable) sections. There are overall graphs for each, and clicking on one reaches details for that particular resource.

It now can show data for each NUMA node. The CPU tab now displays simple percentages on heat- mapping tiles to display utilization for systems with many (6. Variants of the Zotob and Spybot worms have used this technique, for example. Many types of malware also enable this policy setting in the registry.

Rootkits can prevent themselves from getting listed in the Task Manager, thereby preventing their detection and termination using it. See also. Support. Retrieved 2. 01. 2- 1.
