    Windows Defender Antivirus Update Error 0x80070643


    There is a Windows Defender Antivirus update available but I am unable to install it as it is showing error. I have already reboot my laptop and ran the commands on CMD like sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth , but none of them helped out. Please someone tell the solution to fix this error. Here is a screenshot of the update error.

    :)
