After running sfc /SCANNOW in my Windows 10 Pro installation, and getting

"Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log."

I tried to follow the steps here: http://answers.microsoft.com/en-us/windows/wiki/windows_10-update/system-file-check-sfc-scan-and-repair-system-files/bc609315-da1f-4775-812c-695b60477a93

and here http://www.tenforums.com/tutorials/7808-dism-repair-windows-10-image.html

After having created the Windows 10 ISO using the Media Creation Tool and running this command:

DISM /Online /Cleanup-Image /RestoreHealth /Source:esd:G:\sources\install.esd:1 (I have tried to include /LimitAccess to no avail)

I am still getting errors,

"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."

I have tried to reboot, but it is still not fixing anything. (Of course, these commands are being run as administrator).

I could upload the DISM.log file if necessary. The only similar question I could find was this one Windows 8.1 Dism can't find source even when ISO mounted but it refers to a Windows 8 problem and the updates that are suggested are specific to that OS.

So, I was having the same problem, and I was able to solve it using the following method.
I downloaded the Windows Image (ISO) using the Microsoft website. Therefore, I did not want to download another image using a third party website.

To solve this, try following these steps.

  • Download the Windows Image
  • Extract it to a Local Drive. (For example E:/)
  • Make sure it has all the necessary permissions.
  • Make sure your command is correct. (E.g.: Drive Letter, Index number, etc)
  • Try it now.

If it doesn't work, create a new administrator account and try again.  


  • DISM /Get-WimInfo /WimFile:G:\WinISO\sources\install.wim
  • DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\WinISO\sources\install.wim:1 /LimitAccess


To check the index number, run this command.
DISM /Get-WimInfo /WimFile:X:\WinISO\sources\install.wim
( 'X:\WinISO\sources\install.wim' - This should be replaced)

If you are not certain about the commands, please check these websites.

    Note that this link "Download the Windows Image" leads to different pages. Clicking this from my pc will open a page forcing me to download the media creation tool. But when I use my phone it opens a page allowing me to download the .iso directly which is what I think you had intended with your answer. Thanks Microsoft. 🙃

    Update: it turns out that on my phone I was logged in with a Microsoft account from work.

Finally solved it. As I could find out here Windows 10 DISM error: 0x800f081f the ISO created by the Windows 10 Media Creation tool does not work with DISM. I downloaded one from Techbench and managed to use DISM with that one.

I do not know whether it is the fact that the ISO created by the Tool has an ESD file instead of a WIM one, but changing the ISO to the Techbench one (which uses a WIM file instead) and using the adapted command DISM /Online /Cleanup-Image /RestoreHealth /Source:WIM:G:\sources\install.wim:1 did the trick

I cannot accept my own answer for 2 days, so will have to wait to mark this as answered

  • DISM documentation only mentions working with .wim or .vhd(x). I believe an ESD is an encrypted wim.

  • On the second link I included, it was mentioned that an ESD can be used, but I'm not sure. There are people asking how to convert an ESD to a WIM. But well, I suppose you are correct since using an ISO file with a WIM file instead worked great!

  • Old thread that bubbled up, but it may have been that the original attempt used the wrong index. If I recall correctly, on the ISO Windows Pro is maybe index 8. Index 1 is the locked down Windows 10 S. DISM can query the indices of the image.

With this instruction you can convert esd to wim without downloading with external dangerous links:

dism /export-image /SourceImageFile:install.esd /SourceIndex:1 /DestinationImageFile:install.wim /Compress:max /CheckIntegrity

Check with this what index:

dism /Get-WimInfo /WimFile:install.esd
