Notes
Microsoft lists the 3rd Generation Intel Xeon Scalable family in the supported-processor lists for Windows 11 24H2 and 25H2 and for Windows 10 22H2; Microsoft has not published a separate 26H2 list, and the 25H2 entries still apply. Windows 11 additionally requires TPM 2.0 and UEFI Secure Boot on the platform. Server deployments normally run Windows Server or an enterprise Linux distribution.
