Microsoft has updated its hardware support documentation, announcing a shift in the role of the Pluton security processor. On new hardware platforms from AMD, Intel, and Qualcomm, Pluton will no longer function as a TPM 2.0 module.
According to the updated 2026 hardware guidelines, TPM 2.0 requirements will now be fulfilled by manufacturer-provided firmware TPMs, such as Intel PTT, or through dedicated discrete TPM chips located on the motherboard.
Despite this change, Microsoft confirmed that the Pluton architecture remains a part of current and future Windows devices. It will continue to provide a hardware-isolated security environment, though its specific responsibility for TPM 2.0 tasks has been removed.
Microsoft has not provided a specific reason for this architectural adjustment. The company has not disclosed whether the decision relates to supply chain factors, security strategy updates, or technical compatibility requirements.
