Task Manager in Windows  Step by Step Guide ▷ 2020

The task manager is a tool built into Windows operating systems. The same brings with it a wealth of information Useful when measuring the performance of the computer and the system itself.

It has always been used by average users to end applications or programs that are frozen. But the truth is that there are many more things that can be done with it, such as viewing and controlling the activities that are running on the computer.

That said, if you want to know all the functions of this powerful tool, We invite you to stay with us in this entry. Where we will also explain the different ways you have to open it.

What are all the functions of my PC’s task manager?

Beyond the aforementioned, it is used to monitor performance, verify the status of the network, see the users connected to the computer, etc. So that Knowing exactly what this add-on helps you is key to being able to control 100% the functionality of our computer.

Next we will see in detail what its main functions are:

Measure processes

When we open it we can see that it has different tabs, where each one provides different information. The first that we can observe is that of Processes ”, it provides us with the consumption information for each of the applications. This includes:

  • Applications in progress, displayed at the top as “Applications”.


  • Background applications, displayed as “Background processes”.

Background processes

  • Finally, we can also visualize the “Windows processes”.

Windows processes

From each of the 3 different types of applications that are working on our computer, the following data can be observed:

  • CPU: the general CPU consumption that the application in question is causing. This comes in percentages and is measured after having measured the consumption of the application on the hard disk and in RAM memory.
  • Memory: This table measures in megabytes the consumption of RAM caused by the application, service or process that is being evaluated.
  • Disk: In this section you can see the requirement in percentage of the hard disk. In this application every second that passes is measured in MBps.
  • Net: If it is an application that works with the Internet, for example, a Web browser, here you can see how much consumption is generated in Mbps.
  • Energy consumption: This panel, according to all the expenditure observed in the previous lines, shows how much energy this application or process requires. All of this is measured at the same moment.
  • Power consumption trend: Unlike energy consumption, this panel shows the average consumption of the application or service over time.

Application data

  • It should be noted that it is from the tabs Processes “, where the famous action of Finish homework” how much we use when a program does not respond.

Measure overall performance

In the second tab which is called “Performance”, we are going to find a general overview in data graphics about the status of the most important components of the equipment. Which are:


  • CPU: The most relevant data of this component observed in this tab are:

Processor model: easily observable in the upper right corner.

Processor model

Processor capacity in use, speed in Hz and number of processes and threads that are being performed. All of this is visible at the bottom of the graph.

Processor data

  • Memory: in this section we can find the elementary information of our RAM:

RAM capacity and DDR generation: easily observable in the upper right corner of the performance graph.

RAM capacity and generation

Megabyte capacity in use, remaining available capacity, and cache usage. If the latter is very high, cleaning is recommended. It is displayed below the graph.

Memory data

  • HDD: In the disc section we find the performance of this at the moment in its respective graph. In addition to other important information:

Hard drive name and model: easily visible in the upper right corner of the screen.

Hard drive name and model

Read and write speed measured in MBps and net capacity of the hard disk. It’s at the bottom left of the screen.

Hard drive data

  • Net: The last one will be tentative to the Internet connection model that is being used, being “Ethernet” if it is by cable and “Wifi” if it is wireless. Therefore, we will be able to see the metrics of the controllers that are active. If there is no Internet connection, nothing will be displayed.

Network Controller Name and Model: We find it in the upper right corner of the screen.

Network adapter model

Naturally below the graph we will find the Kilobits that are sent and received per second, as well as the main source of the connection.

Network adapter data

Application history

This tab shows us the history of all programs that qualify as an app in our system and the consumption generated during its use throughout the day.

Application history

Application should be understood as all those programs that are installed by default on the system.

Starting the task manager

In this section we will find all the program services that open when the system starts. That is to say, those that just when you turn on the computer are activated.


From here we can deactivate them if we notice that they are having a negative impact on the computer’s startup speed. To deactivate them we must right click on the service and select the “Disable” option.

Disable a startup service


From here it is possible to monitor all the movements of the computer users in case there are different active sessions. You can also view the general consumption metrics of each of the sessions.


This can also be used to detect a program that is slowing down the computer and shut it down.


In it you can see all and each of the processes carried out by each program. It is designed so that experts in the area can put any of them into suspension or execution.




In the last tab we find clearly all the Windows services and each of the computer components. So it is only recommended activate or deactivate under the supervision or advice of an expert.

Steps to open and use the task manager in Windows 10, 7 and 8:

Windows has the peculiarity that it allows you to access the Task Manager as quickly and easily as possible. Let’s see how to do it in the most popular versions currently.

In W10

In Windows 10, you just have to right-click on the taskbar at the bottom of the screen and then choose the option “Task Manager”.

In Windows 8

The interface of the Windows 8 system is similar to that of Windows 10, so the above procedure is totally valid. But, it is also possible to do it by pressing the keys Ctrl + Alt + Del ”. This enables us a menu where you can choose the option Task Manager” easily.

In Windows 7

Finally, in Windows 7 it is the same way, but since the interface is different, here we show you exactly how to do it. Right click on the lower task bar and then choose the option “Start Task Manager.”

Tricks that you surely did not know about the Windows task manager

  • If Task Manager ever hangs or stops working, you can start another one by pressing CTRL + SHIFT + ESC. “Winlogon will search for an existing instance and try to revive it for up to 10 seconds. If that Taskmgr doesn’t start to make sense responding to the secret code in that time, another will be launched. That way you’re never without a Taskmgr as long as there are some resources available.”
  • Task Manager will load in reduced mode if resources are low– For example, it will load only the processes tab if it is what it needs to boot. “It’s one of the few apps that doesn’t ‘crash and go’ when things go wrong.”
  • If the Task Manager gets corrupted internally, kill or close it: Restart it by pressing and holding CTRL + ALT + SHIFT and the Task Manager will reset all its internal settings to factory settings if it detects that key combination at startup.
  • If all the title bars disappear and you only see one graph, double click on the client dead space to switch to normal mode.
  • CTRL + SHIFT + ESC will launch the Task Manager without any help from the Shell. So if the Shell or Explorer is dead, you can use this key combination to start Taskmgr and restart the shell. Even if your taskbar has disappeared, this combination should work.
  • If the shell can’t start something or hangs, try Task Manager– This has a mode where it will load without any reference to shell32.dll and will allow programs like CMD.EXE to be started without the start menu.
  • You can find the binary to run any process in the processes tab: just right click and select “Open file location”.
  • There should be nothing that Task Manager cannot kill– Will escalate privileges (if you have them) and enable debug privileges to attach and kill apps if necessary. “If Task Manager can’t kill it, you have a kernel problem.” Here Plummer notes that after Windows XP some intentional limits were added to what Task Manager can kill to prevent the user from killing essential Windows components and self-infringing a blue screen.
