    Do the error mean Windows Defender isn't working right?

    Not necessarily. Those WD entries look just like false entries that many of us got last July.

    Did you run those earlier DISM commands whilst connected online? If not, do so now.
    This is included in SFC - TenForumsTutorials

    When was your computer last updated?
    - To get your WD version
    - - Double-click on the WD icon in your System Tray [nowadays I should really say, the "Notification area"],
    - - in the bottom-left corner of the WD window click on Settings [the gearwheel icon],
    - - in the left-hand column click on the blue text About,
    - - the line Antimalware client version is your WD version,
    - - the lines Antivirus version / AntiSpyware version give your WD malware definitions version.

    The computer had failed to upgrade from 1809 to 1903 to 1909 unless there were steps made to block upgrades.

    Windows 10 version history - Wikipedia

    https://docs.microsoft.com/en-us/win...0-version-1909
    https://docs.microsoft.com/en-us/win...0-version-1903

    The in place upgrade repair can be performed using any of these iso: 1909, 1903, 1809
    The most up to date version is preferred.
    If there is / are failures they can be troubleshooted.

    Try3:

    I don't have a WD icon in my systray. But if I go to "Control Panel\System and Security\Windows Defender Firewall" it shows Defender is On. Where can I find the version?

    If I check Windows Update, I see the last update attempt for Quality was 1/16/20 which failed and it was:
    "2020-01 Microsoft Edge Update for Windows 10 Version 1809 for x64-based Systems (KB4535547)"

    Previous to that the last Quallty update was successful on 1/14/2020:
    "2020-01 Cumulative Update for .NET Framework 3.5, 4.7.2 and 4.8 for Windows Version 1809 for x64 (KB4535101)"

    The last Definition Update was:
    2/10/2020, Successful: "Security Intelligence Update for Windows Defender Antivirus - KB2267602 (Version 1.309.663.0)"

    All updates listed that failed were repeated and then were successful.

    Also, Yes I was online when running the DISM commands.

    So your WD malware definitions are at Version 1.309.663.0 - mine are 1.309.773.0 so yours will probably reach that state at your next routine update.

    To see the WD UI [user interface] you can also go to the Start menu & select Windows security [which is actually its correct name these days] then you can use my instructions
    - in the bottom-left corner of the WD window click on Settings [the gearwheel icon],
    - - in the left-hand column click on the blue text About,
    - - the line Antimalware client version is your WD version,
    - - the lines Antivirus version / AntiSpyware version entires both give your WD malware definitions version.

    The findings from scannow / restorehealth only indicate a mismatch.
    They don't indicate malfunctioning Windows defender.

    This is a known hash mismatch problem.

    This is from a Microsoft link:


    Cause

    This is a known issue in Windows 10, version 1607 and later versions, and Windows Defender version 4.18.1906.3 and later versions up to version 4.8.1908.

    The files for the Windows Defender PowerShell module that are located in %windir%\System32\WindowsPowerShell\v1.0\Modules\Defender ship as part of the Windows image. These files are catalog-signed. However, the manageability component of Windows Defender has a new out-of-band (OOB) update channel. This channel replaces the original files with updated versions that are signed by using a Microsoft certificate that the Windows operating system trusts. Because of this change, SFC flags the updated files as "Hashes for file member do not match."

    Future releases of Windows will use the updated files in the Windows image. After this change is implemented, SFC will no longer flag the files.



    The troubleshooting should fix the hash mismatch.

    In case the in place upgrade fails it can be troubleshooted.

    Ok, I ran the in place repair, and afterwards when I ran sfc /scannow it says it didn't find any integrity violations.

    Here's the result up setupdiag: SetupDiagResults.log - Google Drive

    I think I'm all set, Windows seems to be running much faster.

    This is my WD info:
    Antimalware Client Version: 4.18.2001.7
    Engine Version: 1.1.16700.3
    Antivirus Version: 1.309.747.0
    Antispyware Version: 1.309.747.0

    Thanks for your support.

    Your WD version is now up to date and your malware definitions are from earlier today so that's also okay.
