DISM error 2

The DISM or Deployment Image Servicing and Management tool, also known as the System Update Readiness tool, helps fix some Windows corruption errors that may cause updates and service packs not to install, like if a file is damaged.

This tool can be used to service a Windows image or prepare a WinRE (Windows Recovery Environment) and/or WinPE (Windows Preinstallation Environment) image, but, it can also be used to service .wim (Windows image) or .vhd/.vhdx (virtual hard disk).

Whenever you try to use the DISM command line and get the DISM error 2 displayed as a message, you may not know the first thing to do in such a case, but there are solutions you can try as outlined below, to fix the error.

How to fix DISM error 2

  1. Temporarily disable or uninstall your antivirus
  2. Check your DISM version
  3. Refresh the DISM tool
  4. Reset your PC with Keep my files option
  5. Use Disk Cleanup tool

Solution 1: Temporarily disable or uninstall your antivirus

Sometimes your security software can get in the way of some of the processes on your computer, so in the case of a DISM error 2 issue, you can temporarily disable the antivirus, or uninstall it, and if the issue persists, you can un-mount the image and check the result again.

Remember to reinstall or enable your antivirus once you’re done.

Solution 2: Check your DISM version

Ensure you’re using the correct version of DISM that is installed with the Windows ADK. Also, do not mount images to protected folders like the UserDocuments folder.

If DISM processes are interrupted, temporarily disconnect from the network, and consider running commands from WinPE instead.

Working in Command Prompt will be like a walk in the park after reading this guide!


Restart and then run an SFC scan in Safe Mode by doing the following:

  • Click Start and then go to the search field box and type CMD
  • Go to Command Prompt on the search results
  • Right click and select Run as Administrator

Solution 4: Reset your PC with Keep my files option

If you’ve tried the system restore and it doesn’t work, reset your PC with Keep my files option.

Performing a reset allows you to choose which files you want to keep, or remove, and then reinstalls Windows, so follow the steps below:

  • Click Start
  • Click Settings

Solution 5: Use Disk Cleanup tool

Since DISM tool won’t work or brings up DISM error 2, and Disk Cleanup can’t release much space, use the Disk Defragmenter to rearrange fragmented data on the system by doing the following:

  • Log in as Administrator
  • Click Start and select File Explorer
  • Expand This PC
  • Right click on Local Disk (C:) and click Properties
  • Go to Tools tab
