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. 

 

How to Fix DISM Error 50 on Windows 10

 

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.”
