    sfc /scannow Errors, Now What?


    OK, so sometimes possibly you're better off not knowing. Running Windows 10, 1909 and everything is functioning perfectly, or so I thought. No errors, nothing, not a single hiccup. Then I run sfc /scannow, maybe just because I'm curious, maybe too much time on my hands. In any event results of first run:
    sfc /scannow Errors, Now What?-first-run.png

    Read here that sometimes you need to restart and run DISM and then sfc /scannow again, so I did. Results of second run:
    sfc /scannow Errors, Now What?-second-run.png

    Did another search here and the suggestion was to run "Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:F:\sources\install.wim:1 /limitaccess" after mounting the Windows ISO image. Did that, results here:
    sfc /scannow Errors, Now What?-final-run.png

    The only thing I see that I'm not sure of is that the DISM version is 10.0.18362.1379 and the Image version is 10.0.18363.1379. Could that be an issue?

    Also, I am running Matthew Wai's "preferences", could those be causing the errors. Prior to that I was running Sledgehammer and I know that there would be errors with DISM and sfc /scannow if that was active. It was completely uninstalled prior to using Matthes Wai's solution.

    If not, where do I go from here? Thanks.

    SFC /VERIFYONLY (check failing) is not the same as failing to repair.

    First check your disk (3rd party tool) and if ok run
    chkdsk X: /scan
    from an admin command or Powershell prompt, where X is the pertinent drive letter.

    If ok, ultimately an in-place upgrade repair install which keeps all progs and data would be appropriate.
    For that you need an iso file of the same major build as you have installed (freely downloadable).

    @Homer712

    The correct order would be first:
    Dism /online /cleanup-image /restorehealth

    and then:
    sfc /scannow

    Source:
    Fix Windows Update errors via DISM or System Update Readiness tool - Windows Server | Microsoft Docs

    The Dism version number does not have to match the installed build number.

    The version numbers of files starts with 18362 because the substructure forms the version number 18362 is Build 1903.

    The same applies to 20h2 or 21h1 because the base is 19041 Build 2004 there.Here is an example picture:

    sfc /scannow Errors, Now What?-screenshot-2021-04-17-202852.jpg

    If Dism cannot provide the defective files or download from the Microsoft servers and thus sfc /scannow cannot repair the files, you should first look in the relevant CBS.log to see which files are defective.

    As it is in the linked Microsoft page.


    Before performing an in-place upgrade, this is always the first thing someone should do who is familiar with the logs.

    @dalchina Thanks, I took it in steps.

    1. Ran chkdsk, results:
    sfc /scannow Errors, Now What?-chkdsk.png

    Then I stepped through the "Image Health" steps 1, 2, 3, 4, 6 and 7:

    sfc /scannow Errors, Now What?-read-me.png

    Last step 7 generated this screen:

    sfc /scannow Errors, Now What?-sfc-scannow.png

    Also, three reports were generated on the desktop. Sadly, for those of us to whom a four or five line batch file is a major accomplishment, they may as well be in Greek. So, I'm looking for help from those who can interpret these reports and advise what my next step should be. Guessing that my choices may be to do a repair of 1909, or just upgrade to the next version. A "clean install" either way would take me ages as I have a large number of additional software installed.

    @Tekkie Boy

    No I had not. I ran the Sledgehammer "uninstaller" but not the "recovery.cmd." Actually, just tried it a couple of times (install/uninstall Sledgehammer) and the uninstall process completely deletes the entire Sledgehammer folder, so I would not have even seen the "recovery" folder.

    But, I copied the recovery.cmd to another location, uninstalled Sledgehammer, then ran the recovery.cmd. Guess what . . . sfc/scannow runs with NO ERRORS. I then ran the "Image Health" version of sfc/scannow (option 7) and it found NO ERRORS as well. So, I'm good to go!

    Thank you for researching this for me and "friendly greetings" back at you!

    I will go up on the Sledgehammer site and leave a link to this thread for the developer. Possibly the issue was at my end, but it's worth him knowing the process I went through to fix things.

    It is absolutely normal to see the following error:
    Code:
    Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.
    Run "Undo everything.cmd" before running "sfc /scannow".
    Re-run "Disable hijackers.cmd" after running "sfc /scannow".

    The update hijackers are system files scanned by SFC.exe. When the files have been disabled (locked), SFC.exe will find such errors.

    Just posted this over on the "My Digital Life" forum in the Sledgehammer thread:

    I don't know how on God's green earth I missed (or just had a complete "senior" moment) the fact that "Matthew's Preferences" disables the same hijackers files that Sledgehammer does. So, when I ran the "Sledgehammer" recovery.cmd, the reason the sfc/scannow errors went away was that the recovery.cmd was undoing the same changes put in place by "Matthew's Preferences" as it would have had I still been using "Sledgehammer."

    Marking thread as solved.

    Edit: For anyone reading this thread in the future, the latest version of Kyhi's "Image Health" (mentioned in Post #2) is located on his profile page: https://www.tenforums.com/members/kyhi.html under the "About" tab.

    Hello @Homer712,

    I will go up on the Sledgehammer site and leave a link to this thread for the developer. Possibly the issue was at my end, but it's worth him knowing the process I went through to fix things.
