    Windows Defender Antivirus - KB4052623 4.18.1910.4 - Error 0x80070643


    Hi everyone,
    i got error 0x80070643 when I try installing last antimalware platform, I had the same error last time but it installed in some way, now it seems impossible.
    Windows update troubleshooter didn' find errors.
    SFC /SCANNNOW found corrupt files but was unable to fix some of them. In the cbs log file I see error in windows platform.
    I resolved some errosr with:
    Dism /Online /Cleanup-Image /CheckHealth
    Dism /Online /Cleanup-Image /ScanHealth
    Dism /Online /Cleanup-Image /RestoreHealth

    but i'm still unable to solve the problem.
    Thanks.

    I don't know why, but Windows now correctly updated defender platform.
    I run again sfc /scannow and now it was able to repair files.
    Windows 10 misteries...
    I hope everything will be ok with next platform update
