Windows Shell Experience Host is a background process in Windows that is launched together with the system and runs until the session is over. Users often ask about the purpose of system processes, and this one is among that category. In very rare cases, the name of that process can be used to conceal the virus which runs in the background. In this post, you will read the detailed review of that process, methods of checking if Windows Shell Experience Host is a virus, and also the removal method for malware that mimics this process.
What is Windows Shell Experience Host?
This process is very important for correct system functioning. First, it is responsible for the correct rendering of the windowed interface – exactly, this kind of appearance gave the operating system its name. Static-design elements, such as Start menu, Taskbar, frames around the opened program, together with notification center, are also managed by the Windows Shell Experience Host.
Another important function, that is used by a big number of Windows users, is the dynamic changing of wallpapers on the desktop, using the slideshow of designated photos or a preset, offered by Windows theme. Its version in the “modern” shape was initially added in Windows 951; all previous versions of the OS by Microsoft used much more specific rendering mechanisms, that have a very low compatibility with each other.
How can I stop the Windows Shell Experience Host?
No way. This process belongs to the system ones, so it is protected from any kind of external interruptions. And there is no need to do it – on modern versions of Windows 10, you will likely spectate a very low consumption for this process. If you see that Windows Shell Host Experience takes more than 5% of your CPU/RAM resources, and you have ensured that there are no viruses on board, try to disable the dynamic wallpapers, and also update your Windows to the latest version.
The times when Windows processes may be disabled to increase the system performance have passed long ago. When Windows XP was the last actual OS version, computers were quite weak, and their upgrade was quite expensive, disabling several services could really make your PC faster without any significant problems. Nowadays, such tricks can make things even worse.
How can I detect that Windows Shell Experience Host is a virus?
Another way to check if the process is launched by a malicious program is to open its file location. Find the Windows Shell Experience Host process in Task Manager, and click it with a right mouse button. Choose the “Open file location” option, and you will see the folder where the .exe file is located. If the Windows Shell Experience Host is located in C:/Windows/System32, everything is ok, but any other location of the source file means that you have malware on your computer.

Frequently Asked Questions
Can I just delete the process from the root directory?
No. In case if the process belongs to the legitimate system element, you will not be able to edit the root directory of the system, where it is stored, without granting yourself permission for this action. And its deletion will surely lead to a system crash without a possibility of loading the system back, because the crucial component is absent.
Is it possible to decrease the hardware consumption of this process?
That process consumes literally nothing, so you will likely see no occasions when there is a need to make it less greedy with resources. However, if you see that it takes more than 20-30% of your CPU and the same amount of RAM, it is likely a virus. Perform the guide I wrote above.
How can I know this process is malicious without checking its root directory?
As it was mentioned in the previous question, the CPU/RAM consumption of the original process is very low. So, the Windows Shell Experience Host that uses a lot of hardware capacity is definitely a virus. Another way to understand that this process belongs to a malicious program is its location inside of the Task Manager.
