CXL support is currently in preview in WS2025. GA of CXL support is TBD.
Would it be possible to have more information about Microsoft support of CXL in Windows, Windows Server and Azure Local ?
Christina and team, is this for 'memory expansion' only or are you saying CXL 'full support' is TBD? or both? i'm a bit unclear as i read it was already available for 'memory expansion' only via cxl. i'm asking because details matter :) to me anyway.
thank you

Official CXL support timeline in Windows Server for any scenario is TBD. The preview support in WS2025 is for memory expansion.
