does anybody knows an out of the box working USB WIFI adapter for (ARM64) Windows 10 IOT Core?
Hello Uwe Steinkohl,
Win10 IOT Core is supported by Microsoft. They do have some supporting information covering WiFi modules on their website so perhaps it may help.

My apologies for the inconvenience! I hope this helps!
