Windows Defender Updates

[doug]

Defender automatically installs definition updates daily on its own without BatchPatch. However, BatchPatch will also install definition updates when they are available and have not yet been installed by Defender. You would need the checkbox for ‘Include “Definition updates”‘ checked in the BatchPatch settings.

The client itself would be a software update, not a definition update. My guess is that Microsoft could deliver it under any of the update classifications ‘Critical’, ‘Security’, ‘Updates’, or ‘Update Rollups’ depending on the particular reason the update was published. Generally speaking in most cases you should leave all of the left-side update classification filter boxes checked in the BP settings.

Thanks Doug. I forgot to clarify that I am using BatchPatch to update PCs on a system without internet, so it is in ‘cached mode’ and ‘offline mode.’ Based on this, does your answer above change at all?

Thank you!

I don’t think Microsoft includes definition updates in the WsusScn2.cab file for offline updating. If they do include it, then BatchPatch will install it, but based on my recollection and a quick test here, they do not include it. I also tested installing the latest cumulative update to see if it included an update for the virus definitions, but it does not appear to include it.

That said, to deploy the latest virus definitions to offline computers you can manually download the definitions file from Microsoft, and then you can use the deployment feature in BatchPatch to deploy it to your target systems.

You can get the updates at the link below. The file is delivered as mpam-fe.exe. You create a standard deployment in BatchPatch ‘Actions > Deploy’, like my screenshot below.
