Here is a optimized shell script to launch your Windows 10 on ARM VM:
If you prefer a clean, stable retail installation rather than an Insider Preview build, you can build a QCOW2 image from scratch using a Windows 10 ARM64 ISO. Step 1: Download the ISO via UUP dump windows 10 arm qcow2
disk image. In practice, it was like trying to fit a square peg into a round hole while the peg was actively trying to rewrite its own physics.
Windows creates frequent background disk writes. To prevent your QCOW2 file from bottlenecking, explicitly set the cache policy and discard flags on your drive device block: qemu-system-aarch64 \ -M virt,highmem=off \ -cpu max \
For years, the dream was to run a "real" desktop OS on a pocket-sized device. When Microsoft released , it didn't just target laptops like the Surface Pro X ; it inadvertently gave hobbyists the perfect tool to experiment on non-PC hardware. 2. The File Format Bridge: VHDX to QCOW2

If you have a Windows 10 ARM image in VHDX format (e.g., from the Windows Insider Preview), convert it using the qemu-img tool:
