i think, i got the reason for this problem.
In the eventlog of my Windows 10-NUC i've got events regarding to an unproper shutdown/poweroff on every boot. I searched the web - it seems to be a bug or known problem with the Fastboot-Option on Windows 10. I've deactivated fastboot and since this moment i've a working CIR on every boot.
I don't tested it but i think after physical PowerLoss you have to boot a second time (with connected AC) for the CIR to work/listed in the Device Manager. Don't know the behaviour but i think, i had the same problems with my NUC D2820. The problem there was, that i turned the power socket off (TV/HiFi-Setup) when i left the room. When Power was restored, the NUC doesn't react on PowerOn/Off-Commands by IR. After you started it one time by hand and shut it down, the CIR On/Off worked again (till you switch the socket off).
Thank you for the information provided,
To continue with the support could you please let us know what is the BIOS version that you have installed on the unit?
