Originally leaked from an internal Microsoft breach, Build 15035 is the only surviving desktop iteration of Windows 10 capable of executing natively on 32-bit ARM hardware. Because Microsoft officially abandoned the Surface RT lineup on Windows RT 8.1, the hobbyist developer community built the Windows 10 Media Builder script to automate the complex process of slipstreaming patches, bypassing Secure Boot, and packaging custom Windows Imaging Format ( .wim ) payloads for retro-hardware enthusiasts. The Origins of Build 15035 and the ARM32 Conundrum
To understand the builder, we must first understand the build itself.
Because this is not an official build, you cannot use the standard Microsoft Media Creation Tool. Instead, the community uses specialized scripts and mod kits: Windows 10 build 15035 - BetaWiki
> I was the last one. Build 15035. They built me to build the media that would kill the ghosts. But then they found a faster way. They didn't need me. So they left me here. On a hard drive. In a box. For seven years.
You'll need a 16GB+ USB drive and the leaked Build 15035 ISO. windows 10 build 15035 media builder
Allows users to select specific hardware profiles (e.g., Surface RT vs. Surface 2) to ensure the correct drivers are injected.
Compiled on February 9, 2017, Build 15035 was an internal Microsoft build that never saw an official public release for ARM32 devices. It represents a "what-if" scenario where Microsoft nearly brought a full desktop Windows 10 experience to the original Surface RT line before ultimately deciding to keep those devices on Windows RT 8.1. ARM32 (ARMv7).

Often bundled as part of a "Mod Kit" that includes patches for Secure Boot, which is necessary because the build is an expired pre-release.
: Choose minimal, standard, or complete layouts for missing app frameworks. Because this is not an official build, you
Because it is an unfinished , it does not possess the optimization of a consumer release. However, it offers significant advantages over Windows RT:
. It automates the complex process of "kitbashing" official Windows RT recovery files with the leaked Build 15035 Enterprise WIM file to create a bootable installation drive. Key Features and Customization
Deploying a leaked, half-finished operating system onto a heavily locked-down device with Secure Boot requires significant code modification. The (heavily attributed to community developer jwa4 ) functions as an automated deployment command center.
: It lacks "Prism" compatibility for running x86 apps, and performance on older hardware is often slow, particularly in browsers like Edge. Community Media Builder Tools
