DISM Host Servicing Process High CPU Usage

In this post, we explore what the DISM Host Servicing Process is. What should you do if it uses too many CPU resources? Can you uninstall DismHost.exe? I will show you several useful solutions for fixing these problems.

What Is the DISM Host Servicing Process?

DISM, which stands for Deployment Image Servicing and Management, is a command-line tool that handles the process of mounting and unmounting Windows image files while installing critical system updates. It is used in the background to deploy and service Windows images safely.

However, regarding the DISM Host Servicing Process or DismHost.exe, there is some conflicting information. Some users claim that it is an important component of the Windows operating system, while some antivirus programs regard it as malware.

In fact, DismHost.exe is a legitimate Windows process. However, sometimes malware may disguise itself as DismHost.exe, which can confuse. Typically, you won’t see any window or icon for this file on the taskbar, as it runs in the background.

Additionally, the DISM Host Servicing Process may lead to several problems, such as:

• Being regarded as malware.
• Causing the Service Host Local System network restricted problem.
• Leading to high disk or CPU usage, usually up to 90%–100%.
• Consuming Internet bandwidth.

Why are so many DismHost.exe in the temp folder?

The presence of DismHost.exe files in the Temp folder is a common issue that users report. It’s often suspected to be a sign of malware. But sometimes there are legitimate reasons why this file might appear repeatedly. This can happen due to errors in Windows system maintenance tasks, such as Disk Cleanup, Windows Update, or Windows Defender scans. These maintenance tasks sometimes create temporary DismHost.exe files to manage operations related to disk imaging, cleanup, and system repair.

If the temporary files are not cleared after the task is completed, they may accumulate over time, filling the Temp folder with multiple DismHost.exe files. Additionally, corrupt system files, incomplete updates, or misconfigured scheduled tasks can also contribute to this accumulation.

Generally, the most common issue is the DISM Host Servicing Process causing high CPU usage. In the following sections, we will show you how to solve the DISM Host Servicing Process high disk usage error.
