UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs, designed to replace BIOS (basic input/output system). This standard was created by over 140 technology companies as part of the UEFI consortium, including Microsoft. It's designed to improve software interoperability and address limitations of BIOS.
Windows utilizes the UEFI to support the handoff of system control from the SoC firmware boot loader to the OS. The UEFI environment is a minimal boot OS upon which Windows devices are booted and the OS runs.
