Hello.

After uninstalling Trellix, I want to reinstall Defender and enable the feature. This fails with error 0x800f0906

In the CBS log I found some CBS Catalog Missings.

KB5019964, KB5023697 und KB5026363: I could find it in the Microsoft Update Catalog, KB5010359 as a link in a post on this forum. They can all be installed by dism... AddPackage.

But the error remains, because KB5005043, KB5008207, KB5006669 und KB4489882 are no longer downloadable in the MUC.

I ask for your support. You probably have a better solution without DISM... AddPackage or something similar to make my server 2016 fit again.

Here's what I've already done

Wusa /uninstall /KB:5019964
The update KB5019964 is not installed on this computer.

Wusa /uninstall /KB:5023697
The update KB5023697 is not installed on this computer.

Brilliant !
The error described here has been solved.
Defender could be installed.
Thank you for the quick support.

You're welcome. Glad to hear that Defender is installed without any issues this time.
