Thank you for this guide!

One suggestion: In the section about converting the Insider Preview VHDX file, you do not need any third party utilities. VMWare Fusion has one included in its app bundle. You can just run the following and it will convert it to a vmdk file:

/Applications/VMware\ Fusion.app/Contents/Library/vmware-vdiskmanager -r ~/Downloads/Windows11_InsiderPreview_Client_ARM64_en-us_25276.VHDX -t 0 ~/Downloads/Windows11_InsiderPreview_Client_ARM64_en-us_25276.vmdk
