I need help using Dism /Online /Cleanup-Image /RestoreHealth to fix corrupt system files. I tried sfc/scannow, and it said it found corrupt system files, but can't fix them. I then proceeded to look up this issue, and it told me to use the Dism command. Here is the error that I got:

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

Keep in mind that I'm repairing my actual system, not an ISO.

Please help me!

  • look in CBS and DISM logs which files are missing. – magicandre1981 Jan 14 '17 at 16:44
  • Found this: 'Session: 30567853_2897710740 failed to perform store corruption detect and repair operation. [HRESULT = 0x800f081f - CBS_E_SOURCE_MISSING]' in CBS.log – Lucas C. Jan 14 '17 at 17:05
  • Actually I don't think that it has anything to do with missing files, it just can't find a mounted ISO in the default location. This is not what I'm trying to do, I'm trying to fix my system, not an ISO, so I don't know what could be happening. – Lucas C. Jan 14 '17 at 17:10
  • Download the ISO, mount the ISO, and use the wim file contained on the ISO as the source. – Ramhound Jan 14 '17 at 19:13
  • share the CBS and DISM log folder and I'll look what fails – magicandre1981 Jan 15 '17 at 8:06

Looking at the logs, shows that 1 file is damaged:

(p) CSI Payload Corrupt x86_microsoft-windows-w..ywmdmshellextension_31bf3856ad364e35_10.0.14393.0_none_5f441c558cd56176\audiodev.dll

10.0.14393.0 is the Anniversary update of Windows 10, so get a clean ISO, double click on the ISO to mount the ISO and run

Dism /Online /Cleanup-Image /RestoreHealth /source:wim:D:\sources\install.wim:1 /limitaccess

(where D: is your mounted Win10 1607 ISO)

Now DISM can fetch the required audiodev.dll from the install.wim.
