Dism Host Servicing Process (DismHost.exe), a Malware?




There are conflicting information about Dism Host Servicing Process (DismHost.exe). Some say it is a genuine Windows process, others say it is a malware.

There are some claims that DismHost.exe is related to cleanmgr.exe. Others say, it is related to DISM (Deployment Image Servicing and Management). From my experience and research, there is not evidence to support these claims.

I decided to write a guide about Dism Host Servicing Process to provide research-based information about this process. My conclusion is that based on the way it presents itself, DismHost.exe is a malware and needs to be removed.

In this guide, I will examine the symptoms of a typical malware. Then compare it to how Dism Host Servicing Process presents itself. Finally, I will share proven steps you can apply to clean your computer and rid it of DismHost.exe.

Let’s begin by defining Dism host servicing process.

What is Dism Host Servicing Process?

DismHost.exe is a Windows process that creates multiple copies of itself, creates multiple files in temp folders, causes high CPU and high disk usage.

According to reports from different Windows users, Dism Host Servicing Process creates hundreds, sometimes thousands of files in C:\Windows\Temp and/or \Users\<UserName>\appdata\local\temp folders.

Multiple users have also reported this process causing extremely high CPU and disk usage in task manager.

The next logical question I need to address is this: Is DismHost.exe a malware?

My direct answer will be, Yes. But don’t take my word for it. Lets examine the symptoms of a typical malware and compare it to how DismHost.exe presents itself (its symptoms). Then we will make a decision.

First, lets examine how a malware typical presents itself when it infects a computer.

  • Slow computer
  • Your computer may crash with blue screen of death (BSOD)
  • Disk space filling up with unknown files

Now that we have established that DismHost.exe is a malware, it is time to show you how to remove it from your computer.

Here are the high-level steps:

  • Download and run Microsoft’s Malicious Software Removal Tool
  • Delete all files and folders created in Temp folders

  • Next, select the type of scan. I recommend Quick scan for a start.
I recommend you start with Quick scan as full scan may take too long to complete. If the tool finds Dism Host Servicing Process (DismHost.exe) it will recommend a full scan anyway.
  • The malware removal tool will start running. Wait for it to complete the scan and report back.

  1. This is an incredibly assumptive and anecdotal article at best. Assuming Microsoft’s system files are malware because they bloat the machine is a big assumption. You haven’t been able to explain at all why it happens even though you mention all this research you did, and didn’t give guidance to anything substantial either. It took me 5 minutes of research to find people that solved their problems with this file and you didn’t even suggest that either.

    • Hi Brock,

      Thank you for taking the time to leave a comment. I take time to research my articles and ensure that I only share information I believe to be accurate. I can assure my readers that I am not just a tech writer, I worked in the tech industry (Specifically, Microsoft technologies) for over 18 years. So, my articles are hands-on and not just theoretical.

      Having said that, I encourage feedback to allow my readers to share their view as well. The tech community is full of smart guys like yourself (indulgence not intended).

      Will you be kind enough to clarify some of your statements. Once you provide additional clarifications I will verify them and If credible, I am happy to amend portions of the article.

      Thanks again,
