This stick is going to be woefully underpowered for Windows. It has only 4GB of RAM - that will barely run Windows alone.
I disagree. Windows10 runs pretty well on even little Dell tablets with only 2GB of ram and no significant processor power. On one of these compute sticks it should actually run fine.
And Windows on IoT SoC boards - why? Windows only makes sense if you want to exploit the Windows development ecosystem. Which is nonexistent for those small IoT boards.
These boards don't use an on-board dev ecosystem, they use a dev PC and download the resulting code. To be fair, you could use the command line
