The Microsoft Devices Team is excited to announce Project Mu, the open-source release of the Unified Extensible Firmware Interface (UEFI) core leveraged by Microsoft products including both Surface and the latest releases of Hyper-V.
(...)
These enhancements allow Project Mu devices to support Firmware as a Service (FaaS). Similar to Windows as a Service, Firmware as a Service optimizes UEFI and other system firmware for timely quality patches that keep firmware up to date and enables efficient development of post-launch features.

Quelle bonne idée ! Comme ça, la prochaine fois que MS se prendra les pieds dans le tapis, le PC ne démarrera plus du tout
