    sfc /scannow failing after this latest Defender Platfom update.


    Anyone else seeing this after last night's Defender Platform update that went from 4.18.1905.4-0 to 4.18.1906.3-0?

    I'm getting it on both my platforms. Both machines are on the latest 1903 207 build.

    Perhaps some Powershell Defender module for 4.18.1906.3-0 hasn't synced up yet?

    One I fixed with DISM /Online /Cleanup-Image /RestoreHealth. The other I'm waiting to see if it gets fixed by the CU in the next hour.

    SFC /SCANNOW Errors After Update


    I've just updated a Windows 8.1 Pro PC to Windows 10 using the Techbench ISO which updated without any problems. However, I've just run sfc /scannow and it found errors it could not repair. I have managed to get sfc /scannow to run without errors - see what I did below:

    1. Ran sfc /scannow which showed error "Windows Resource Protection found corrupt files but was unable to fix some of them."
    2. Ran Dism /Online /Cleanup-Image /ScanHealth which reported "The component store is repairable."
    3. Ran Dism /Online /Cleanup-Image /RestoreHealth which failed with 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."
    4. Mounted the W10 Techbench ISO and ran Dism /Online /Cleanup-Image /RestoreHealth /source:wim:G:\sources\install.wim:1 /limitaccess which reported successfully "The restore operation completed successfully."
    5. Ran sfc /scannow wich completed successfully with report "Windows Resource Protection found corrupt files and successfully repaired them."

    Please advise:
    1. Why would sfc /scannow fail on a newly updated installation which ran sfc /scannow error free immediately before the upgrade?
    2. Why did I have to use install.wim from the Techbench ISO at step 4 above for Dism /Online /Cleanup-Image /RestoreHealth to work and will I have to use install.wim from the Techbench ISO every time I need to run this Dism command?
    3. How can I configure my PC so it has the correct install.wim file for the Dism command to work properly?

    SFC /SCANNOW Errors After Update


    1. Why would sfc /scannow fail on a newly updated installation ...
      In addition to what essenbe said .... there is a known issue re: opencl.dll - it's been around for a while. If it is opencl.dll (follow SFC Command - Run in Windows 10 - Windows 10 Forums), the error can be ignored.
    2. Why did I have to use install.wim from the Techbench ISO ...
      I'm not sure, but it seems to indicate that the Component Store cannot be found (resolved). I think this would cripple your system though instead of only showing up in DISM.
      Try the Windows Update Troubleshooter (TS) in Control Panel - then try https://support.microsoft.com/en-us/...troubleshooter (I'm not sure if they are the same, but why would MS offer a diag cab separate from the built-in TS?

      Please copy the C:\Windows\Logs\CBS (the entire folder) into a compressed folder on your desktop and attach the zip folder to a post. If it is too large, copy just the CBS.log file into a compressed folder and attach that.
    3. How can I configure my PC so it has the correct install.wim ...
