Notes: Skylake-W predates the 8th-generation-or-later requirement on Microsoft's supported-processor lists for Windows 11 24H2, 25H2 and 26H2, so Windows 10 is the newest Windows release that is supported. Current Linux distributions install and run normally on this workstation platform; ChromeOS is not applicable and macOS is tracked for Apple-designed cores only.
