If you turn off 1 of 7 background tasks in Task Manager, your computer may freeze, freeze or crash the operating system. So you have to memorize the names of these tasks.

If you refer to the Task Manager, there will be times when you wonder what the background tasks in this Windows Process list are for. And if you try to turn off some of these background tasks, what will happen? We will answer for you 07 of the important background tasks that you should never try to turn off in Task Manager, specifically as follows.

System (ntoskrnl.exe)

“ntoskrnl.exe” also known as NT Operating System Kernel, is a system file of Windows, it is responsible for many tasks such as hardware emulation, memory handling, and provision of kernel and real classes. executable for the Windows kernel space. In addition, this file is also responsible for managing and compressing temporary files (page files) to reduce memory usage.

Warning: Do not disable background tasks in Task Manager 1

ntoskrnl.exe shows up in Task Manager as “System”. And this can also be understood as an important system file, so Microsoft naming it System is not easy to understand.

If you turn off System (ntoskrnl.exe), the consequences will be extremely severe. Since critical drivers such as disk access and USB devices rely on the System to do its job, closing this process locks the system and requires a hard reboot. If you need to restart the System (perhaps when troubleshooting high CPU usage), you should restart your computer normally.

If you notice the System running at high CPU levels frequently, this may be a sign of a hardware problem.

Windows Logon Application (winlogon.exe)

As the name suggests, the Windows Logon Application needs to work every time you start your computer because it is through it that you can log in to use Windows. So after logging in, can we turn off Windows Logon Application?

The answer is No!

The first function of the Windows Logon Application is to load user data when you log in. Any changes to the registry that you have previously made are saved for your account only, and they will all be reloaded when you log in, thanks to this process.

Winlogon is also extremely important for security. Once you’re signed in, this will provide you with security options and display them on the Windows Security screen, which includes some quick links for you to change your password, sign out, and perform. perform the same operations.

In addition, Windows Logon Application is also a task that provides quick screen lock options or displays Screensaver. If you try to use the End Process command on the Task Manager, Windows will warn you that this is not a good idea.

If you try to do that anyway, your Windows will go to a completely black screen and there is no hope of recovery. At this point, you will have to restart the computer for the process to run again.

Windows Start-Up Application (wininit.exe)

Windows Start-Up Application is the process that keeps Windows stable when you log in for the first time and keeps the system running for the entire time it is used.

The most important function of Windows Start-Up Application is like a springboard for most applications and processes that run in the background every time you start Windows. This includes starting other important processes such as “lsass.exe” and “lsm.exe”.

Warning: Do not disable background tasks in Task Manager 5

The Windows Start-Up Application will run until you shut down your computer. If you try to disable this process, you will receive a Windows prompt warning. And just like Windows Logon Application, if you turn it off, the system will hang to the point of needing a reboot.

Client Server Runtime Process is considered as one of the essential Windows processes. However, now the role of the Client Server Runtime Process has changed throughout the evolution of Windows. Previously, this process handled all the graphical elements of Windows. But now, it only assumes responsibility for handling a few background functions.

The two most important roles of the Client Server Runtime Process are shutting down Windows (Shut Down) and launching the “conhost.exe” process, which launches the Command Prompt. It doesn’t seem like much, but it’s an important process. If something goes wrong and the process doesn’t run at startup, you’ll get a blue screen error.

As you might have guessed, if you ignore Windows’ advice and proceed to turn off this process, the system will freeze.

Windows Session Manager (smss.exe)

Windows Session Manager has been around since the time of Windows 3.1 version, and it is also one of the important background processes.

Whenever Windows is about to start, Windows Session Manager performs a few preparatory steps. It will proceed to map the drives and create virtual memory paging, etc. Once done, it will invoke the Windows Logon Application process and you will see the login screen appear.

Warning: Do not disable background tasks in Task Manager 7

Apparently, the Session Manager persists after you log in. It monitors both the Windows Logon Application and the Client Server Runtime Process to wait for either process to terminate.

If something happens to the Windows Logon Application and Client Server Runtime Process, Windows will shut down as usual. But if either process terminates unexpectedly, Windows Session Manager will freeze the computer.

Windows Shell Experience Host

This is a new process that appeared in the Windows 10 version. And it mostly works with the new elements of the Windows 10 version.

If you’ve used a previous version of Windows, you may have noticed the new changes Windows 10 makes to apps like the clock and calendar. The Shell Experience Host process processes these elements, along with the Start menu or Taskbar color and transparency effects.

In addition to the updated look, the process also works to display Store apps in a window. If you use a slideshow as your wallpaper, you can thank Shell Experience Host for making that possible.

Unlike many other processes in the above list, disabling the Shell Experience Host process will not damage your system. Instead, Windows will restart it after a few seconds. But there’s no reason to close the Shell Experience Host because doing so won’t change the look and feel of Windows.

Windows Explorer (explorer.exe)

The Windows Explorer process will take on the role of handling most of the Windows graphical interface that you use every day. But what happens if you turn off the Windows Explorer process in the Task Manager?

Disabling Windows Explorer will not only close any open File Explorer windows, but will also render the Start menu, Taskbar, and System Tray unusable. However, restarting Explorer is actually very easy and sometimes automatic.

Warning: Do not disable background tasks in Task Manager 9

As of Windows 8.1 and later, you can right-click Windows Explorer and select Restart to immediately shut down and relaunch the process. If you’re using Windows 7, you’ll have to right-click on it and select End Process, then go to File > Run new task and type “explorer.exe” to get it working again.

There are other ways to restart File Explorer if needed, so keep them in mind the next time you accidentally end a Windows Explorer task.

The processes that this article provides are unlikely to be the only important processes running in your Task Manager. But they are all important to your Windows experience in some way and by now you should know what they are for, right?

Thankfully, in most cases, Windows prompts and protects you from the wrong actions of shutting down an important process by mistake, so you don’t have to worry much.

End: Above is a list of 7 important background tasks in Task Manager that you must not turn off. If turned off, there is a good chance that some unexpected problems will occur. So please keep in mind.
