How to Fix DISM Host Servicing Process Issues?

Scan your device with antivirus

The first logical option to do is to scan your device for malware. Many users reported that malware was behind this unusual DISMhost.exe activity in the background of their computers.

A virus/malware is known for its ability to replicate by itself and run behind existing services or files. A full scan with premium antivirus software can find such viruses and eliminate them. Click here for the best antivirus recommendations.

Use /SFC scannow command

If your antivirus detected no malware, the issue could be caused by corrupt or missing files in your system.

We recommend running the /sfc scannow command; it is a windows tool that scans the integrity of your windows files and replaces any corrupt ones if found.

To do so:

  1. Right-click on the Windows button on your bottom left corner of the screen.
  2. Click on Windows Powershell (Admin)
  3. Click Yes on the pop-up box to allow the app to make changes to your device.
  4. Write /sfc scannow and press enter. 
You must have admin privileges when running this command, or else it will not function.

The scanning process might take some time; sit back and wait for it to do its job.

Disable the Superfetch service

This method is another way to fix the DISM Host Servicing Process high CPU problem.

Superfetch is another service that pre-loads your applications into RAM to make them launch faster and improve your system.

It is not very recommended to disable this feature; on the other hand, it can be a solution to your DISMhost.exe problems. If disabling it did not affect your dismhost.exe problem, we advise you to turn it back on.

Steps for disabling the Superfetch service:
  1. Press Windows + R buttons together
  2. Type' services.msc' in the Run command
  3. Find Sysmain, double click on it
  4. Under startup type, select disable
  5. Press Apply, then OK
  6. Reboot your PC

To re-enable the service, follow the same steps from 1 to 3, and switch disabled to Automatic.

Stop the Background Intelligent Transfer Service (BIT)

Your next option can be disabling the BIT service. It is similar to the superfetch service but it functions with transferring files online.

To disable this service:
  1. Press Windows + R buttons together
  2. Type' services.msc' in the Run command
  3. Find Background Intelligence Transfer Service, then double click
  4. Press on the Stop button if the service is running.
  5. Change startup type from Automatic to Disabled
  6. Press Apply, OK
  7. Reboot your PC

Once you do that, open Windows Registry Editor.

  1. Press Windows + R buttons together.
  2. Type Regedit and hit enter
  3. Expand the HKEY_LOCAL_MACHINE key
