Windows 10: KB4052623 Install Fail (Error 0x80070643): A suggested workaround.

Hi all

I've seen a number of threads online about "Update for Windows Defender antimalware platform - KB4052623 (Version 4.16.17656.18052)" failing to install (Error 0x80070643).

About a week after the 2018-05 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4100403), I noted the above message in my own update history.

I got some ideas online I turned into a workaround that worked for my circumstances.

In the hope it may work for others, I've posted it on Microsoft Community at KB4052623 - Microsoft Community.

If posting a link to another forum rather than putting the workaround here is acceptable, I'd be really grateful as - being image-intensive - it was a bit long to set up.

Cheers



:)

error 0x80070643 (update)

Hey

Try to apply the update manually As suggested by Microsoft. I just wrote a
step by step guide.

However be sure that the update itself is downloaded and that the installation part is failing, and not the downloading part.

Hope it helps you
