    sfc /scannow errors


    Important thing to remember is that the SFC / SCANNOW cannot always fix all errors at once. It is quite often required to run SFC /SCANNOW several times.

    I have often had a situation that only a third, fourth or fifth run has finally reported "No more errors".

    This is how it should be done:

    • SFC / SCANNOW
    • If SFC reports not all errors were fixed, reboot and run it again
    • SFC / SCANNOW
    • If SFC again reports not all errors were fixed, reboot and run it again
    • And so on

    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 error repair

    Hi,



    Thank you for writing to Microsoft Community Forums.



    We appreciate the efforts you have taken in trying to resolve this issue. I have analyzed the error logs that you have shared and I would suggest you follow the steps mentioned below:



    1. Type Command Prompt in the
      search bar
      on the Taskbar.
    2. Right click on the Command Prompt icon and select
      Run as administrator.
    3. Now, paste the following command and hit Enter:
      DISM.exe /Online /Cleanup-image /Restorehealth
    4. Once the DISM command is executed, we would suggest you to run sfc /scannow again.


    If the integrity violations are not repaired after running sfc scan, the best option will be performing a repair installation. A repair installation will repair all the corrupted files.



    Refer the steps mentioned below:



    Download the Windows 10 Media Creation Tool (MCT) and use it to perform a repair installation
    of Windows 10. We have a video that can show you how if you aren’t sure



    Let us know the results.



    Regards,
