To discover more about Windows 10 IoT Core development visit the Windows 10 IoT website.
Microsoft also said it is in talks with Element14 about pre-loading Windows 10 IoT Core onto Pi devices.
However, with its 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU and 1GB RAM the Raspberry Pi 3 might be powerful enough to run a full version of Windows. And that would be an interesting development.
Begin Pi 3 coding with my Learn Python on the Raspberry Pi tutorials.
