System requirements

Hello, I would like a bit more information about the system requirements of Avast Free Antivirus(not One).

Windows 11 except Mixed Reality and IoT Edition;

I want to get more information from this. I don’t understand. Does this mean I have to uninstall Mixed Reality? Or does it mean that it is not required? Also I don’t really understand what is “IoT” edition.

There are several editions of Win11.
You can use Avast Free on Microsoft Windows 11 Home / Pro / Enterprise / Education but not on Windows 11 Mixed Reality and Windows 11 IoT (Internet of Things) editions.
