The most efficient way to install this build is through community-developed tools like the Windows 10 Media Builder. 1. Preparation & Downloads

Before starting, ensure you have a Windows-based PC to create the installation media and a USB drive (at least 8GB).

The rain drummed a relentless, rhythmic beat against the windowpane, a grey slate of a sky mirroring the dreary task ahead. I sat down, the hum of my desktop PC vibrating slightly through the desk. It was time. The main rig was acting sluggish, haunted by the ghosts of drivers past, and I decided a clean slate was the only cure.

But not just any clean slate. I was chasing a ghost.

I navigated through the murky waters of archived tech forums, past the broken links and dead ends, until I found it: Windows 10 Build 15035.

This was a specific moment in time—an Insider Preview build from the "Creators Update" era, early 2017. It sat right on the precipice of stability and the bleeding edge. It was famous for introducing the first iterations of Game Mode and the consolidation of the Control Panel settings into the modern Settings app. For a retro-tech enthusiast, it was a sweet spot.

I clicked the link for the Media Builder. The file, tiny and innocuous, downloaded in a blink. I ran the MediaCreationTool.bat—or rather, the specific utility wrapper that allowed the creation of media for this specific, now-obsolete build number.

The User Account Control prompt flashed, a jarring blue rectangle asking if I was sure. I clicked Yes.

The Media Builder interface materialized on the screen. It looked harmless enough—that standard, clean Windows 10 aesthetic. The background was a soothing blue, the progress bar a sterile white. It asked the usual questions with polite indifference.

What do you want to do? Create installation media for another PC. I selected the radio button and clicked Next.

The architecture screen popped up. I unchecked "Use the recommended options for this PC." I wanted to be specific. I toggled the drop-downs: Language: English (United States), Edition: Windows 10 Pro, Architecture: 64-bit (x64). It felt like ordering a rare wine.

The Builder paused, thinking. It reached out to the Microsoft servers—or at least, it tried to find the remnants of the packages still hosted on their legacy CDN. There was a long pause, the cursor spinning into the blue circle. For a second, I thought the link was dead, the digital equivalent of a rotted bridge.

Then, the progress bar jumped to life.

Getting a few things ready.

I watched the digital gears turn. The Media Builder isn't just a downloader; it's a carpenter. It wasn't just grabbing a file; it was stitching together the Install.ESD, verifying the integrity of the build, and preparing the boot sectors. windows 10 build 15035 media builder install

I selected USB flash drive as the vessel. I plugged in a 16GB SanDisk drive, its red LED blinking expectantly.

The process began in earnest. The UI was sparse, offering no percentage points, only the phrase: Creating Windows 10 media.

Behind the scenes, I knew the chaotic dance that was occurring. The Builder was formatting my USB drive, scrubbing away old family photos and installers

Windows 10 Build 15035 is a rare, leaked pre-release version of the Creators Update that is significant because it is the only known build compiled for ARMv7 (32-bit ARM). It is primarily used by enthusiasts to unofficially install Windows 10 on older hardware like the Surface RT. 

Because this is a leaked, unofficial build, there is no official Microsoft "Media Builder" for it. You must typically use a community-developed "Image Builder" or manual deployment script to create a bootable installer.  How to Build the Installation Media 

To install this build on a device like a Surface RT, you generally need to follow these steps found in community guides like i12bretro's tutorial: 

Obtain the ISO/WIM: You must find the Build 15035 ARM32 files (often hosted on sites like BetaArchive).

Use a Secure Boot Exploit: Devices like the Surface RT are locked. You must use a "Golden Keys" exploit or a specific UEFI exploit script (e.g., Yahia's installer) to allow non-official OS booting. Prepare the USB: Format a USB drive as FAT32.

Use a tool like Rufus or manual diskpart commands to make it bootable.

Apply the install.wim image to the USB using a deployment script specifically designed for the ARM32 build.

Boot from USB: Hold the Volume Down button and press Power on the Surface RT to boot into the installation environment.  Important Limitations 

Unsupported: This build is highly unstable and will never receive security updates.

No Prism: Unlike modern Windows on ARM (which is 64-bit), this 32-bit build lacks an emulation layer to run standard x86 (.exe) apps.

Driver Issues: Many hardware components (like Wi-Fi or GPU acceleration) may require manual driver injection during the media building process. 

Update Microsoft Surface RT Tablet to Windows 10 [Unofficial Upgrade]

Functionality: The tool automates the download of necessary image files, configures them for specific hardware (like Surface RT), and applies patches. Key Features: It allows users to:

Choose between "Minimal," "Standard," or "Complete" app packs.

Remove bloatware like BitLocker, Cortana, and Windows Defender to save resources on low-RAM devices. Integrate the Office 2013 RT Suite. Installation Requirements & Steps Windows 10 | Open Surface RT - GitBook

For Windows 10 build 15035 (a pre-release Insider build from the Creators Update development cycle), a useful feature when using a media builder or installer is the ability to perform an “in-place upgrade repair” without needing a later build.

Here’s the specific, actionable feature:

Feature: Clean installation with built-in “Skip TPM / Secure Boot” check bypass
Since build 15035 predates many hardware enforcement policies, its installer allows installation on older or non-compliant hardware (e.g., legacy BIOS, no TPM 2.0) without manual workarounds. This makes it useful for testing on virtual machines or retired PCs where later Windows 10 builds refuse to install.

How to use it with a media builder (e.g., Rufus, Media Creation Tool for that build):

Why this is useful:
Later Windows 10 builds (e.g., 20H2 and beyond) enforce stricter hardware checks. Build 15035 bypasses those, making it a lightweight, portable environment for low-resource systems or debugging legacy software/hardware compatibility. The Windows 10 Build 15035 Media Builder install

Note: This build is outdated and insecure for daily use. It’s useful only in isolated, offline environments for testing or archival purposes.

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.
