Windows task manager

One of the most common and in most cases useful tools to determine the performance of the system is the Task Manager. Open Task Manager using any of the following methods:

• Press Ctrl-Shift-Esc.

• Right-click an empty area of the taskbar, and then click Task Manager.

• PressCtrl-Alt-Delete, and then click Task Manager.

• Type “taskmgr” / ”taskmgr.exe” in prompt command line

Applications Tab

The Applications tab will show you all running programs that can be interacted with by the currently logged in user. Here you can start new programs (tasks), close currently running programs or switch to task you need to work with.

1. To launch a new program, click New Task... Then type your command or click Browse to locate the application. This function works in the same way as Run does in the Start menu.

2. To exit a program, select the program and click the End Task button. This feature is useful when you have an open program that is no longer responding to input commands. Task Manager can help you exit such programs, but you may lose all unsaved information.

3. To bring up an open program, select the program and click Switch To. The program will pop to the front.

Processes Tab

The Processes tab displays a list of all the running processes that are on the computer. Unlike the Applications tab, this tab has the ability to display all programs that are running even if they were started by another user or the operating system itself. To list all processes press “Show processes from all users”.

This list indicatesthe amount of CPU power that the process is currently using, how much memory it is using, and a description of the process. To add/remove columns you have to:

· Open to the View menu and then select “Select columns”. This will open a screen where you can enable other columns of information for each process.

Also if you need more detailed information you can:

·Highlight necessary process -> Right Click - > Properties.

At theprocesses tab you can terminate process which is causing problems (not responding, or it is suspected that the process is related to malware, etc.). And also you can terminate not only the process itself but all associated processes by choosing End processes tree.

WARNING: It is possible to terminate processes that are required for Windows to operate properly. Please only terminate processes that you know will not affect the operation of Windows. Some processes that you should avoid terminating if they are located in the C:\Windows\System32\ folder are smss.exe, svchost.exe, lsass.exe, winlogon.exe, and csrss.exe. You can check if they are located in the C:\Windows\System32\ folder by right-clicking on the process name and selecting properties.

1. To end the process of a currently running application, right-click the application's entry in the Applications tab and click Go To Process. The applicable process will be highlighted in the Processes tab.

2. To end a highlighted process, click End Process. You'll want to terminate an application in this manner when clicking End Task in the Applications tab doesn't work.

3. Right-click a process and then click End Process Tree to end the process and all associated processes.

Services Tab

This tab will show you all the Windows Services currently configured in Windows. A Windows Service is a special type of program that is started by Windows when it starts or as necessary and runs in the background performing a particular task. You can also start and stop an individual service by right-clicking on a service and selecting Stop or Start, and detect associated processes by selectingGo To Process.
