That looks like a 64-bit Arm CPU, so QEMU will happily run both 32-bit and 64-bit x86 guest code on it in both system emulation and linux-user emulation modes. If you're asking specifically about limitations in whatever Microsoft's x86 emulation is, you'd need to ask Microsoft about that, since it's not a QEMU thing. thanks -- PMM
