Microsoft distributes Windows updates and certain recovery images in a highly compressed format called ESD (Electronic Software Download). Unlike the more familiar ISO (International Organization for Standardization) image, an ESD file is not directly bootable. It is encrypted, compressed, and often lacks the folder structure needed for USB installation media or virtual machines. For users of Arm64 devices — such as the MacBook Pro with Apple Silicon (via virtualization), Lenovo ThinkPad X13s, or Windows Dev Kits — obtaining an official Windows 11 on Arm ISO can be frustratingly difficult. Microsoft prioritizes x64 downloads on its public pages, leaving Arm users to extract the necessary files from update packages or UUP (Unified Update Platform) sets.

Download the tool and convert your Windows 11 ARM ESD files to ISO files with ease. w11arm_esd2iso
