What is DISM host servicing process?

DISM or Deployment Image Servicing and Management is a command-line tool in Windows used to create a Windows preinstallation environment in the background. 

DISM can also be used to count packages and enable or disable Windows services. However, DISM is a recursive process that can self-replicate in temporary folders, causing system slowdowns and using too much storage or CPU.

How to prevent high CPU usage by DISM host servicing process?

Here are a few solutions you can try out if the process is causing headaches for you.

Run a malware scan

Since the process usually runs pretty quietly in the background, the chances are that this is malware or virus posing as one instead of being a Windows process. In such cases, run a full, in-depth system scan using your antivirus or antimalware of choice, and if you find anything suspicious, remove it from your PC.
