There is no retail version of Windows for ARM. It only comes pre-installed on ARM devices, or through some partner channel when you form a business deal to sell ARM devices. Last I saw the current way to get Windows on ARM was by extracting it from an old Windows IoT project build. So it's novel and interesting when someone figures out how to work around all these roadblocks to get Windows working on a consumer ARM SBC.

Maybe that was true previously but these days you can just download a disk image for Windows ARM ready-to-go from https://www.microsoft.com/en-us/software-download/windowsins...

Especially given Windows NT, back when it was called that, was portable, and supported various RISC processors.

When working on Win2k it started off still trying to support MIPS and PPC but then shipped only x86 and Alpha

I thought Win2k on the Alpha was cancelled, too, although they made a Beta. There was an article posted here on HN recently from 1999 about Microsoft cancelling Win2k on Alpha.

(Sorry for being a smartass about it.)

I remember shipping SP6 and 6a still supporting 4 arch. And we were still testing 2k on x86 and Alpha in my group (NLB). Ages ago, can't hardly remember.

And this is what I hope ReactOS will become one day, in spite of Microsoft's FUD campaigns.

The fact that it runs without hacks or fiddling with drivers?

Raspberry Pi 4 supports UEFI, and Windows 10 already worked on it. So, not too surprising.
