Have you ever seen a process called “Windows Shell Experience Host” in the Task Manager window? If you have seen, do you know what this process is? And why does it sometimes “eat” more CPU and computer memory? This article will explain the process of Windows Shell Experience Host on Task Manager.
What is the process of “Windows Shell Experience Host”?
“Windows Shell Experience Host” is an official part of Windows, which is responsible for displaying the universal app in the windows interface. It also handles several graphical elements of the interface, such as the Start menu, change the transparency of the taskbar and bring new images to the notification area, calendar, etc. This process even checks Controls certain components of desktop background operations such as changing the background when setting up for presentation.
When new to Windows 10, many users have problems with the “Windows Shell Experience Host” CPU and memory usage. Although the updates have somewhat remedied this problem, some users still report issues related to the Windows Shell Experience Host.
Why is it using too much CPU and memory?
In normal operation, “Windows Shell Experience Host” will not consume CPU, sometimes they increase to few percent when graphical elements are changed, but then decrease to zero. This process usually uses memory fluctuations in the range of 100-200 MB. You will also see this situation from time to time but then stabilize again. However, if you find that the process often consumes more CPU or memory than normal, such as using up to 25-30% CPU or several hundred MB of memory, you need to fix this problem right away.
Update your computer and application universall app
The first thing you need to do is update your Windows, which can be a good remedy. Next you also need to update all the universal app applications. To update, open the Windows Store, click on the user icon next to the Search bar and then select “Downloads and Updates”.
In the “Downloads and updates” window, click the “Check for updates” button and then, if there is an update, click on “Update all“.
After updating, wait a while to see if the problem has been resolved. If not, read the next section to find out some of the causes of the problem with the “Windows Shell Experience Host” process.
Check out the common causes of multiple CPU usage problems
If the above solution does not fix the problem, check the following common causes by trying one by one, if not correcting the changes and switching to another cause.
The most common cause of this problem is due to running slideshow background in Windows. Of course, this problem is not always the case, you will see a few hundred megabytes of memory each time the background changes and the CPU usage goes up by 25% but does not change after that. To test this, go to Settings> Personalization> Background and change the background to Solid color or Picture. Also, you should run slideshows with another application, such as John’s Free Background Switcher or DisplayFusion (the free wallpaper management features available in the free version).
The next potential cause is for Windows to automatically choose a color based on the wallpaper. To check for this, go to Settings> Personalization> Colors and uncheck “Automatically pick an accent color from my background” then wait to see if the problem is fixed. If this is not the cause, re-install the above and move on to the next cause.
The next possible cause may be due to transparency effects for the Start menu, taskbar and Action Center. To access this setting, go to Settings> Personalization> Colors and turn off the “Make Start, taskbar, and action center transparent” option.
Is it possible to disable the “Windows Shell Experience Host”?
The answer is no, you can not disable the “Windows Shell Experience Host“, and should not do so. This is an important part of distributing images in Windows 10. You can temporarily end this process to fix the problem by right-clicking it in Task Manager and selecting “End Task“. Windows will automatically restart the process in a few seconds.
This process can be a virus?
“Windows Shell Experience Host” is an official Windows component and it is not a virus. Although we have not seen reports of viral entry into the process yet, it does not mean that it is not possible in the future. If you suspect malware, scan your computer with your favorite antivirus software.
