in UP Board Windows
Hi all, I have just installed Win 10 IoT Pro 64bit OS into my UP board and after installing the MS Windows 10 64bit Drivers Package, it still shows 3 unknown device in the Device Manager. I have checked the Unknown device properties and the values are APCI\HAD022A8\1, ACPI\80862288\1 and ACPI\80862288\2 respectively. Can anyone help to resolve my issue..? Thank you..

    Hi

    The HAD022A8 device is a virtual device related to HDMI audio driver loading on Linux. This won't affect you on Windows as HDMI audio works anyway on Windows without it. We may be able to remove this device entry from the ACPI table in the future.
    The 80862288 devices are PWM controllers. These are relevant only if you specifically wish to use the PWM functionality on pins 32 and 33 of the 40-pin header. Otherwise, you can safely disregard this device. As far as I know, further additional drivers may be required for Windows to enable the I/O functions on the 40-pin header.
