Since the last reply was a few months ago, I wanted to say I have a RPi 3b+ running Windows IoT Core.
- WiFi and BLE are not working with these steps (Ethernet does work)
I used the IoT Core Dashboard: https://docs.microsoft.com/en-us/window ... /downloads
I downloaded the 17661 preview build (.iso) from here: https://www.microsoft.com/en-us/softwar ... windowsiot
I used 7zip to extract the .iso file.
I used 7zip to extract the .msi file within the new folder.
Then using the IoT Core Dashboard, in "Setting up a new device", specify a custom OS build by selecting the Windows_10_IoT_Core_RPi3B+.ffu
file from the new folder created by extracting the .msi.
I did not realize at first those extraction steps were needed. They are are not documented. Once I got past that, my RPi 3b+ booted up. It does take a few minutes the first go round.
I hope this helps...
