  1. CBS Log not showing any corrupted files after SFC scan found and repaired.


    Hi,I run a C: backup about once a week. But before the backup, I run SFC /scannow. Sometimes I get "found corrupted files and they were repaired.So looking as the CBS Log file and can not find any repairs listed. I do a search in the CBS file for "corrupted" and it does not find any.To be safe I then run dism /online /cleanup-image /restorehealth ThenSFC /scannow. No corrupted files foundI will then run my backup of the C: driveMy Question is. Should I think I have a virus or is it do to windows update or false positives?I have never in all my years fixing windows have had this issue. Any tho

    :)

    SFC reports corrupt files that cannot be repaired

    Hi Jay,

    For to better assist you with the SFC reports issue, we'd like to know the following:

    • Have you installed any Windows updates prior to this issue?
    • Please provide us a CBS logs for us to determine what is the file that cannot be repaired.
    To get the logs, please follow the steps below:

    • Open a Command Prompt (Admin).
    • Copy and paste findstr /c:”[SR]” %windir%\Logs\CBS\CBS.log >”%userprofile%\Desktop\sfclogs.txt”, then hit
      Enter. (This will create a sfclogs.txt file on your desktop).
    • Open the sfclogs.txt and check the result of SFC scan.
    Note: SFC cannot always fix corrupted files.

    We're looking forward to your reply.

    Understanding the CBS log & repairing corrupt files

    Thank you so much for your help! I ran:

    Repair-WindowsImage -Online -RestoreHealth


    Windows Resource Protection found corrupt files and successfully repaired 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.

    I then rebooted.

    Then I ran:
    c:\>sfc /scannow

    Beginning system scan. This process will take some time.

    Beginning verification phase of system scan.
    Verification 100% complete.

    Windows Resource Protection found corrupt files and successfully repaired 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.

    Then I ran:
    PS C:\> Repair-WindowsImage -Online -CheckHealth

    Path :
    Online : True
    ImageHealthState : Healthy
    RestartNeeded : False

    PS C:\> Repair-WindowsImage -Online -ScanHealth


    Path :
    Online : True
    ImageHealthState : Healthy
    RestartNeeded : False

    I am not sure whether the corrupted files were repaired or not because the "Repair-WindowsImage -Online -RestoreHealth" said it made repairs & then sfc /scannow said it found & made repairs.

    I did notice that I ran all these from C:\ & Brink's tutorial has it run from C:\Windows\System32. I don't know if that makes a difference.

    Does it look like my files should be OK now or is there something else I should do to check?

    CBS Log not showing any corrupted files after SFC scan found and repaired.

    Understanding the CBS log & repairing corrupt files

    I've been getting some event errors lately, in particular 2 errors.

    Date: 10/21/2019 8:54:17 AM
    Type: ErrorEvent: 1020Source: Microsoft-Windows-Perflib

    The required buffer size is greater than the buffer size passed to the Collect function of the "C:\Windows\System32\perfts.dll" Extensible Counter DLL for the "LSM" service. The given buffer size was 34008 and the required size was 45368.

    Date: 10/21/2019 2:07:45 PM
    Type: WarningEvent: 1008Source: Microsoft-Windows-Perflib

    The Open procedure for service ".NETFramework" in DLL "C:\WINDOWS\system32\mscoree.dll" failed with error code The system cannot find the file specified.. Performance data for this service will not be available.

    So I went to https://support.microsoft.com/en-us/...rrupted-system and ran

    sfc /scannow

    I got the message:
    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.

    I tried to follow the rest of the steps listed on the support page, but got lost in the details.

    1. When I used an elevated Powershell & ran the suggested command, I got:

    PS C:\> findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

    out-file : Could not find a part of the path 'C:\%userprofile%\Desktop\sfcdetails.txt'.At line:1 char:1+ findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\s ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OpenError: CBS Log not showing any corrupted files after SFC scan found and repaired. :)) [Out-File], DirectoryNotFoundException + FullyQualifiedErrorId : FileOpenFailure,Microsoft.PowerShell.Commands.OutFileCommand

    2. I manually went to C:\Windows\Logs\CBS & opened CBS.log.There was so much detail that I couldn't follow what was corrupt. I've attached the log.

    I would appreciate anyone telling me what files are corrupt & how to replace them. Thank you in advance!
