    Firmware Showing Yellow Triangle - Surface Embedded Controller, System Aggregator and Surface Touch. I have applied all Windows updates. This happening on a brand new Surface Pro 4. NOTE: We did upgrade it from Windows 10 Pro to Windows 10 Enterprise.
    When I try to update the firmware, it tells me the "best driver is already installed. I have tried disabling and uninstalling it and re-installing it which did not resolve the issue. I downloaded and ran the Windows Surface driver/firmware pack which did not resolve it either.
