There are different tribes within Microsoft, maybe if the Windows kernel team is still functional they might be able to pull it off (I would be surprised if they hadn't the kernel working on ARM all along, and Windows NT originally was a multi-architecture operating system (according to Wikipedia: initially 32-bit x86, DEC Alpha, MIPS and then later PowerPC, Itanium, ARM(!), and 64-bit x86).
