Windows 10 is popping up in some odd places, like old phones and ARM boards. It’s all unofficial, of course, but it might still serve to spark some interest in taking Microsoft’s operating system to places where Microsoft itself might have given up on. We’ve seen both Windows RT and a smidgen of Windows 10 on ARM running on Lumia phones. Now Dutch developer Bas Timmer, a.k.a. @NTAuthority, has brought Windows 10, again its ARM version, to a device that Microsoft already half supports: the Raspberry Pi 3.
