How to Repair a Corrupted Windows 10 Image using DISM

[Lutfij]

Microsoft has included a number of administrative and functional tools at the end users disposal should the need for them arise. The corruption of your Windows 10 installation is always a pain. For those with slow internet connections or limited resources, a re-installation of Windows 10 is not always possible. With that in mind Microsoft has included a tool whereby you can repair your OS's installer image using the Deployment Imaging and Servicing Management tool (DISM for short) and correct any underlying/hidden corruptions.

Follow these steps to get your Installation Image into proper form.

■Open the “Start Menu” by clicking the “Start Button” in the lower left corner of the screen or by tapping the “Windows” key on your keyboard.




■Type CMD




■Right click CMD and run as an administrator(this is what's know as an elevated command prompt)

■There are a couple of ways you can identify, locate and rectify the damaged file(s):

• a| To quickly check if the image corruption is caused by a failed process and whether it can be repaired

• Dism /Online /Cleanup-Image /CheckHealth

• b| To check for component store corruption

• Dism /Online /Cleanup-Image /ScanHealth

• c| To check if the image is suffering from component store corruption, performing automatic repair work while also outputting the findings on a log file

• Dism /Online /Cleanup-Image /RestoreHealth

• d| Using a install.wim to act as a basis for a good versions of corrupted files and use it to repair your image

• Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:Directory Path and location to install.wim file:1

  or
  

  Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:Full Path to install.wim file:1 /limitaccess

  (to prevent DISM using Windows update for online images)
  
  Example:
  Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:F:\sources\install.wim file:1 /limitaccess

• e| Using install.esd to act as a source for good version of corrupt files and repair the corruption type the following

• Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:Full Path to install.esd file:1

  or
  

  Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:Full Path to install.esd file:1 /limitaccess

  
  Example:
  Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:C:\$Windows.~BT\Sources\Install.esd:1 /limitaccess
  or
  Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:G:\Sources\Install.esd:1 /limitaccess
  (where G is the drive letter for your USB device)

■If you've performed any of the steps outlined in Step 4 then you are advised to reboot your system for settings/repairs to take action.
