Raymond Chen at Microsoft recently blogged about this (in multiple posts).
I think it starts here: https://devblogs.microsoft.com/oldnewthing/20260311-00/?p=112134

Hi John,

Another source to obtain Qemu for Windows :

Thanks Vortex!

Nice find - https://www.qemu.org/docs/master/system/target-arm.html

"QEMU can emulate both 32-bit and 64-bit Arm CPUs. Use the qemu-system-aarch64 executable to simulate a 64-bit Arm machine. You can use either qemu-system-arm or qemu-system-aarch64 to simulate a 32-bit Arm machine: in general, command lines that work for qemu-system-arm will behave the same when used with qemu-system-aarch64."

Guess Google AI not so much I 

Not sure how hard to set up, but I'll be reading more.  Won't be windows on ARM but command line capability I'm supposing, unless a ARM Windows ISO can be involved.

Qemu for Windows can emulate ARM64, ChatGPT says :

Code Select Expand

qemu-system-aarch64 \
  -machine virt \
  -cpu cortex-a72 \
  -m 4G \
  -bios QEMU_EFI.fd \
  -drive file=windows_arm.qcow2,if=virtio \
  -device virtio-net-device \
  -netdev user,id=n1

But expect trial-and-error with:

Storage drivers
Display (often -device ramfb or virtio-gpu)

I tested PellesC 14 RC2 using:

• https://github.com/xecronix/JJsRoadRage
• https://github.com/xecronix/crude
• https://github.com/xecronix/MightyEagleC

and a few Windows GDI "projects" I have in my dev folder.  All worked perfectly.

Right. Apparently it was the other way around: emulating X86/X64 on ARM. Oh, well...

I'd really like to be able to do that.  However a brief check came up with this -

"AI Overview
No, standard
x64 Windows 11 cannot directly run ARM64 applications or host an ARM64 virtual machine using native hardware virtualization. Hyper-V on x64 hardware does not support running ARM64 operating systems. To run ARM64 apps, you must use a device powered by an Arm-based processor (such as Windows on ARM or Apple Silicon)."

Sadly,

EDIT: A those 7Zip headers are just a total mess.

Hence my personal policy...
