  1. Failed Updates (Error 0x80070643)


    I have recently purchased a new laptop and made the necessary recent updates, however 2 updates continue to fail to install.


    Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.281.1453.0) - Error 0x80070643


    Update for Windows Defender Antivirus antimalware platform - KB4052623 (Version 4.18.1810.5) - Error 0x80070643


    I have done some research online in order to troubleshoot this failure, however there does not seem to be a clear fix, install, or patch.


    DISM and SFC were both ran in the admin command prompt, however both failed.


    Since the laptop is new I tried the reset function however it did not work. Trying to rollback the updates also did not fix this issue.


    Can I please get some assistance on this matter, as I am perplexed as to receiving these errors on a new system.


    Thanks in advance.

    :)

    Win 10 update failed to install error 0x80070643

    Hi,

    The error code 0x80070643 is commonly caused by .Net Framework installed on the computer. We suggest addressing the 0x80070002 error code first because this issue occurs when some files in the Windows Update are missing. We can solve this error code by following
    the troubleshooting steps suggested on this article.

    Note: The troubleshooting steps for Windows 8.1 also applies to Windows 10.

    Update us with the outcome so we can provide further assistance.
