Are you facing the DISM Host Servicing Process High CPU Usage issue? You are not alone! Many Windows PC users have complained on tech forums about facing errors with Dismhost.exe. We have written a complete troubleshooting guide to help our readers fix the issue in no time. Without further ado, let us begin with understanding a few details about the DISM host servicing process.
What Is The DISM Host Servicing Process?
The DISM Host Servicing Process (dismhost.exe) is a process designed by Microsoft to assist in the functioning of the Deployment Imaging Service and Management Tool (DISM). Its main role is to manage and service Windows images when the Windows OS is being updated or repaired.
The Dismhost.exe is located in C:\Windows\System32\. If you find this process running from another location, then it could be malware pretending to be a legitimate process. This is a safe process when it runs occasionally, but you should be concerned if it spikes the CPU constantly and indefinitely.
Why Does DISM Host Servicing Process Show High CPU Usage?
The actual dismhost.exe designed by Microsoft might use more CPU resources in certain scenarios, like –
- When DISM or SFC tools are launched on the Windows PC.
- Windows updates are being installed.
- If the Windows system image is being repaired, the dismhost.exe spikes CPU usage.
- Managing system recovery features.
However, you need to be concerned if the DISM host servicing process is using high CPU constantly. This might be due to –
- Windows update files corruption
- Corrupted System files
- Malware infection
