  1. Security Intelligence Update for Winodws Defender Antivirus - KB226760


    My WIN10 PC, running v 1903 reported code 0x80070643 as it sought to download a Windows Defender Antivirus update. I didn't know Windows Defender Antivirus was running as I use only AVG. I manually downloaded WIN10 update v 1909 hoping the latest Microsoft WIN10 update would fix the problem but this hasn't helped. I have tried all suggestions made by Microsoft Community Forum, without success. I've also completed an "In-Play" (?) update of Windows, again without success.

    I guess I can just ignore the error message but it would good if there is a general solution if other users have suffered this problem.

    :)

    How to Update Security Intelligence Definition Version for Windows Defender Antivirus in Windows 10


    Windows Defender Antivirus is a built-in antimalware solution that provides next generation protection for desktops, portable computers, and servers.

    Windows Defender Antivirus uses security intelligence to detect threats. Windows 10 will try to automatically download the most recent intelligence via Windows Update to protect your device against the newest threats.

    You can also manually check for updates. A manually triggered update immediately downloads and applies the latest security intelligence. This process might also address problems with automatic updates. Windows Defender Antivirus and other Microsoft antimalware solutions provide a way to manually trigger an update.

    Security Intelligence Update for Windows Defender Antivirus - KB22676

    Is this new? Just got what I thought was a Defender Definition Update, but the name seems to have changed now to
    Security Intelligence Update for Windows Defender Antivirus. Same KB number, same numbering sequence, just a name change. Even Reliability History show some with Windows Defender Update today, then this one just now.

    Not a Platform Update, that remained at 1907.4.

    Anybody else?
