How to Fix DISM Error 50 on Windows 10

Are you looking for solutions to fix DISM error 50 on Windows 10 so you can scan or repair Windows components?

DISM helps the system perform several servicing tasks in Windows. It executes, repairs, and modifies several programs and commands, but like every other tool, DISM can sometimes fail to perform. 

 

 

One of the common errors DISM displays on Windows 10 is ‘Error 50’. This error occurs when the user is trying to run one of the following commands:

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /RestoreHealth

The main cause behind this error is a misplaced registry key. DISM assumes that the command is being executed from a location within the Pre-installation Environment (WinPE) or Windows Recovery Environment (WinRE) instead of an Operating System. This results in error 50 that states, “DISM does not support servicing Windows PE with the /Online option.”

If you have been experiencing DISM Error 50 on Windows 10, you’re in the right place. 

This guide will introduce you to some simple steps you can follow to solve the error.

If the methods mentioned above did not solve the DISM error 50 on your PC, you should try resetting BIOS to its default settings. 

BIOS (Basic Input/Output System) is responsible for managing data flow between the Operating System and external devices such as the hard disk. Resetting BIOS will reboot the Output/Input System to the last saved configuration. 

To reset BIOS, follow the steps mentioned below. 

1. Access BIOS on your PC. For this, you must press the BIOS key set by your manufacturer. These keys are different for each PC. 
2. Once you have accessed BIOS on your PC, access the Default Option entry. 
3. Your screen will display Reset to Default and Factory Default options.  
4. Choose your preferred option and confirm changes. 
5. Lastly, restart your PC and your PC should work fine now. 

Resetting BIOS will solve the DISM error 50 without damaging the data in your PC. However, it best to try this method only if none of the other methods mentioned above work.
