Windows runs on everything from USB thumbdrivess to supercomputers. Windows 10 also runs on phones and games consoles. The IoT version runs on the Raspberry Pi etc. I'm not sure how many of those I'd want to count, but Windows 10 on a Asus T100 looks like a legitimate PC to me, whatever IDC says ;-)
