Create a fresh Windows 10 Pro ISO file with Microsofts Media Creation Tool. (I created a Windows 10 Pro 64 bit German ISO image)

Save the created image on your SmartOS global zone.

cp ... /zones/Windows10_64de.iso

These intructions might work, but they need a bit of attention. I've been reading through ipf and smf documentation and have found a few ways to improve this process. When I have time I'll add that information here, until then, be sure to look into the ipf settings if you're having issues with routing. Good luck!

This is a modified version of sjorge's instructions for Single IP with NAT. Those instructions can be found here: https://docu.blackdot.be/snipets/solaris/smartos-nat

The primary difference is that this version does not rely on etherstubs for internal switching, but instead uses a vlan configuration. The benefits of this method over using etherstubs are:

1. Project Fifo (project-fifo.net) can create vms and zones with vlans, but does not currently have etherstub support.
2. Vlan switching is supposedly more efficient than creating an etherstub to handle switching. I have not tested this statement.
