Hello

We would need to know how this announced incompatibility affects our case and it is necessary to take some action. On the other hand, we do not quite understand what impact the following paragraph has on us: While only Windows 10 version 21H2 and higher are incompatible, the Cortex XDR agent will disable the affected security engine in Windows 10 version 20H2, since it must be disabled prior to the upgrade to Windows 10 version 21H2.

What "affected security engine" do you mean? From the "Impact" section, how does it affect us if the BTP module is disabled? Can anyone respond to out question

Hi @OtisMclaughlin , Welcome to the forum!

There is a bit to unpack here, but I'll keep it concise. This announcement was originally announced on Oct 2021, and affects endpoints which meet the following criteria:

Cortex XDR agent version 7.2.1 - 7.3.3 and 7.4.0
Windows 10 version 20H2 (build 19042) and above
Intel Tiger Lake or AMD Zen-3 processors

To answer your question: the sub-components listed in the "Impact" section will be disabled due to incompatibility. What it means is: the affected endpoints won't be secured against any attacks that are protected by those sub-components, one of them being BTP. You can read up on BTP's here.

What you can do is to upgrade affected systems to Cortex XDR agent 7.3.4 or higher, 7.4.1 or higher, or 7.5.0 and higher, and 7.6.0 and higher.

You should also note that the affected versions (v7.2, v7.3 and 7.4) are nearing end-of-life, so you should review your endpoints and upgrade them inline with your organizational upgrade strategy.
