Deferment of Partner Dev Center SBOM Validation

• The WHCP SBOM requirement (Device.DevFund.Security.SoftwareBillofMaterials) is deferred and will be enforced by Hardware Dev Center for CRA compliance beginning in H2 of 2026. However, Microsoft recommends all driver submissions to include SBOMs. Additional guidance for Device.DevFund.Security.SoftwareBillofMaterials will be provided in advance to H2 2026.
• Partners will be given notice as soon as there is a set enforcement date during a future release, along with guidance on how to meet any new requirements.

• WHCP continues to support a secure supply chain throughout our signing process. That said, the EO on Cyber Security is a call to action from the U.S. Government, so we continue to encourage that our partners seek to enable a secure supply chain as stated in the NIST guidance.
