Windows 10: Windows Defender Antivirus - KB2267602 (Definition 1.273.32.0) - Error 0x80070643

Hi,


I am unable to install Widows Update
"Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.273.32.0) - Error 0x80070643"


It's clean installation of Windows and after update, this is the only update which cannot be install.



When I try to update Windows Defender only, I still get an error message, see below


Windows Defender details:


Threat definition version: 1.237.0.0

Version created: 22 February 2017

Last update: 22 February 2017


When I click "Check for update" it said:

Protection definition update failed.

Error code: -2147023293

Error description: Fatal error during installation.


Any Idea how to fix this?

I follow this guide:

But no luck.


Thanks,

Neb
