First up, Windows 10 IoT on ARM does not support standard UI desktop applications, and does not support Intel architecture applications at all.

A future version of ARM Desktop Windows may support i386 (32-bit, not 64-bit) applications, but that probably will not extend to the Pi - it will be devices based on a new crop of Qualcomm chips.

You would be better to look at something like a LattePanda - an Intel system board that actually runs Windows 10. However, it does cost a lot more than a Pi.
