Windows 10 Build 15035 is a leaked development build of the "Creators Update" and remains the only known client version of Windows 10 available for ARM32 (ARMv7) architecture
. Because Microsoft officially abandoned ARMv7 devices like the Surface RT after Windows RT 8.1, this build is used as an unofficial upgrade
via specialized community tools rather than the standard Microsoft Media Creation Tool. Prerequisites & Tooling
To build the installation media, you must use a community-developed "Media Builder" tool on a separate Windows PC. Media Builder Tool : A script-based tool (often Windows 10 Media Builder
) that automates downloading and patching the leaked ARM32 build. : A USB flash drive (at least 8GB-16GB). Hardware Compatibility : Primarily used for Surface RT
. Note that Surface 2 requires Secure Boot to be disabled, whereas Surface RT generally does not. Step 1: Preparing the Media Builder Extract the Tool : Download the Windows 10 Media Builder and extract it directly to the root of your drive to avoid path errors. Run as Admin : Navigate to the folder, right-click , and select Run as Administrator Configure Build Options Phase 3: Installing Windows 10 Build 15035 You

: The tool will download necessary files and prepare the image. This typically takes around 30 minutes depending on your internet speed. Step 2: Creating the USB Media
Important Note: This is not a standard consumer ISO. It is an internal Microsoft build used for testing on ARM64 devices (like the Lumia 950/XL, Surface RT successors) and early Snapdragon PCs. Installing it on x86/x64 PC hardware will fail unless you are using a specific emulation layer or have an old ARM32 device.
You now have a clean, bootable ISO. Here is how to install it on a physical machine or virtual machine (VM).
Before diving into the media builder process, let’s clarify what Build 15035 is—and isn’t.
Because Microsoft never released this build to the public via normal channels (it was distributed only to partners and internal testers), you cannot find an official ISO on Microsoft’s servers. Instead, enthusiasts use a media builder—a script-based tool that reconstructs the original installation media from raw file fragments or a UUP (Unified Update Platform) set.
Build 15035 contains over 700 known unpatched vulnerabilities, including EternalBlue (CVE-2017-0144). Never connect it directly to the internet. Use a NAT network in a VM, or physically unplug the network cable after installation. Do not log into Microsoft accounts or browse the modern web – HTTPS certificates will fail anyway.
Windows 10 Build 15035 offers a unique historical look at Microsoft’s internal deployment tools. Its Media Builder, while rough by modern standards, successfully generates bootable Windows 10 installation media. Following the procedures outlined in this paper—from clean installation of the build to generating ISO/USB output—enables technicians and researchers to utilize this legacy tool. However, given the build’s expiration and security status, it is recommended only for controlled, offline environments or virtualized labs.
Build 15035 (rs2_release.170210-1550) is a 64-bit-only pre-release version of Windows 10 Professional. Key characteristics include:
