I have install W10 ARM on my Raspberry Pi 3 B+ with WoA Installer, with this procedure https://github.com/WOA-Project/WoA-Installer-Rpi/blob/master/README.md . The Raspberry start correctly and the preparation of Windows too. But when Win sarted, I have an error DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS.
Please be sure that you have adequate power. USB can be disruptive if things are marginal. Best way to proceed is a powered external hub; plug your USB devices in downstream. Once you’ve got a stable system and have a feeling for how things should work, experiment with eliminating the hub.
Additionally, you may want to start without any devices plugged in. It shouldn’t be that way, but some others have had success with that method. You just plug in your keyboard/mouse after you’re in the setup.
