Not really. Microsoft compiled a version of their OS for ARM devices - creatively named "Windows on ARM", but on a Raspberry Pi I'd hardly describe the performance as "running" - walking/crawling would be more apt.

If DOSBox runs on one, then the old DOS-based Windows versions might work. But then, they didn't keep much in System32, where they even had it at all.

They've made Windows IoT Core that runs on Raspberry Pi. I have a colleague that maintains a tanning bed system that uses two Pis running that for each bed, one to operate the bed itself and one to accept payments.

It's mad
