How to Troubleshoot DISM Host Service Processing High CPU Usage Issue

DISM Host Servicing Process is a process that helps Windows Update and other servicing operations to work correctly. If you are experiencing high CPU usage with this process, don’t worry – you’re not alone. In this blog post, we will show you how to troubleshoot this issue. We will also provide some tips to help reduce the CPU usage of the DISM Host Servicing Process.

What is DISM Host Service Processing?

DISM stands for Deployment Image Servicing and Management. It is Microsoft software that runs in the background in Windows and other programs. The command-line tool is used to configure a Windows Preinstallation (Windows PE) image environment.

Thousands of DISM host maintenance process files have been discovered by several Windows users. They are located in the folders C:Windows/Temp/ or Users/AppData/local/temp. DISM can also add/remove drivers, list packages and enable/disable certain Windows features. The most disturbing aspect of DISMHost.exe is that it duplicates itself in temporary directories. This leads to a large amount of hard disk usage.

On the other hand, DISMHost.exe does not open in any window. Its icon also does not appear in the taskbar. It can only be found in the C folder, the Applications folder, the User folder, or the Temp folder.

Why is the DISM Host Service process causing high CPU load?

DISM Host Service or DismHost.exe process can also be dangerous because it can self-replicate in temporary folders. As a result, the system may slow down due to high hard disk load. This is not standard behavior for this file. Some say it is an important component of the operating system, while some security tools consider it a threat.

Besides the fact that the malware takes control of the DISM host service process, many other things can make it consume too much CPU power. Maximum CPU and hard drive utilization over a long period of time can lead to overheating problems and a significant drop in performance, so this problem should be investigated as soon as possible. Another possibility is that some of your system files are corrupted.
