Notes
Atom C-series server and embedded processors do not appear on Microsoft's supported processor lists for Windows 10 22H2 or Windows 11 24H2, 25H2 and 26H2. Appliances built on them typically run Linux, FreeBSD-based firewall software or Windows Server, and mainstream Linux distributions support them.
