    Error 0x80070643 updating Microsoft Defender definitions.


    Greetings. I tell them everything to put them in context. On Wednesday I formatted my desktop PC, since it had not been maintained for a long time and some programs were already working very slow. I upgraded everything smoothly and proceeded to install my programs. Unfortunately I made a mistake when installing ArcGis, it is a program that requires you to install the license before the software, and if the necessary steps are not done it simply does not work. So I had to format again, but today when wanting to install windows updates, I get error message 0x80070643 in windows defender update. I thought it would be solved by installing all the other updates, but no. All other updates install successfully. SO Windows 10 Pro 64 bits

    :)

    Definition Update for Windows Defender - KB2267602 (Definition 1.217.1180.0) - Error 0x80070643

    When updating my version of Windows (Windows 10 Pro x64, Version 1511, OS Build 10586.218) in Windows Update I get the following error: Definition Update for Windows Defender - KB2267602 (Definition 1.217.1180.0) - Error 0x80070643 and am asked to retry.

    I am using Norton Security Deluxe version 22.6.0.142 with the firewall enabled and windows firewall disabled.

    Any suggestions on how to download definition for Defender?

    Regards,
