How to Fix DISM Error: 0x800f081f The source files could not be found

When the System File Checker (sfc.exe) says it found integrity violations but couldn’t repair some system files, the next thing you should do is run the DISM tool with the /RestoreHealth option to fix component corruption. However, when running the following DISM command, error 0x800f081f may appear in some systems:
Dism /Online /Cleanup-Image /RestoreHealth

Error: 0x800f081f
The source files could not be found.
Use the “Source” option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077.
To fix the error, you will need Windows Installer .ISO:

Once you have mounted your Windows Installer .ISO, open up an elevated Command Prompt and depending upon whether you have install.esd or install.wim in the \Sources folder of your Windows setup disk, run one of the following commands:

Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:E:\Sources\Install.wim:1 /limitaccess
Or another command is:
Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:E:\Sources\Install.esd:1 /limitaccess

And here's the raw output during my attempt:

I managed to repair DISM Error: 0x800f081f on a live Windows Server 2016 without a reboot is required, and I'm pretty sure this solution will work on Windows 10 too.

I hope this solution works for your issue as well. Let me know if you find this post useful by commenting down below 👇
