Cover image

Being a Windows user, you might have faced issues like slow performance while browsing the internet or playing video games.

You might have also encountered the crashing of the system with a blue screen of death (BSOD).

Issues like these often make you believe your system is compromised by viruses, or attacked by malware. You might never know the root cause, but running malware scans often fixes the problem.

However, in severe cases, it can get worse. Therefore, it is necessary to find the root cause instead of running different scans without any underlying knowledge.

DISM host servicing process or DismHost.exe could be the possible reason. It is one of the essential background files for running windows operating system (OS). You might think how the DISM host servicing process could be a threat then? Well, according to many experts it does not cause any issue if the DISM.exe is correct and updated.  However, others believe that it is malware itself.

In this article, we will explore what the DISM host servicing process is, what are the issues faced by DISM, and how we can fix them!

What is DISM host servicing process?

DISM is the short form of Deployment image servicing and management.

It’s a Microsoft program found in Windows among other background services. And it’s used to prepare windows preinstallation environment (Windows PE) or for windows image.

DISM also finds its application in adding/removing drivers, enumerating packages, or enabling/disabling some windows features. The alarming thing about DismHost.exe is that it creates multiple copies of itself in temp folders. This is how it causes high disk usage.

Many Windows users reported to have found thousands of DISM host servicing process files in C:\Windows\Temp and/or \Users\<UserName>\appdata\local\temp folders.

However, DismHost.exe does not open in any window. Neither does its icon appear on the taskbar. It can only be found in folder C, Program files, User folder or temp folder. According to experts,

  • It is 34% dangerous if found in C:\Windows
  • It is 19% dangerous if found in C:\Program Files, and
  • 28% dangerous if found in User’s previous folder
