Windows update fails and Windows Defender service cannot start

Question

Hello.

Whenever I try to update a Windows Server 2019 there is an update that always fails:

Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.349.1608.0)
Install error - 0x80070643 (see attached image)

The WinDefend service cannot be started (see attached image)

It looks like there's something to be cleaned up..

Can anybody help me sort this out?

Thank you and best regards.

Answer 1

Hello.

Anybody on this?

I can add that I found this: https://learn.microsoft.com/en-gb/windows/deployment/update/windows-update-resources
but because this server includes WSUS and SCCM (that controls WSUS), I though I'd better ask for advice on this forum.

Can I safely run the wsus reset components commands suggested in that microsoft document on my sccm server?

Can anybody help me sort this out?

Thank you and best regards.

Answer 2

Hi there,

I would suggest you to manually Install the KB updates from the update catalog
https://www.catalog.update.microsoft.com/Search.aspx?q=edge

Please try to run the .Net Framework repair tool and check if that helps.
