Windows 10 Build 15035 Media Builder 〈PROVEN × Checklist〉

The is an unofficial community-made tool designed to create installation media for running Windows 10 on older ARMv7 devices like the Microsoft Surface RT and Surface 2 .

Using the Media Builder is a straightforward process. Here's a step-by-step guide:

Everything changed following a Microsoft data breach in early 2017. A rare internal copy of —the only known full client version of Windows 10 compiled for the ARMv7 architecture —was discovered. It leaked to the public via BetaArchive in November 2019, triggering an ongoing enthusiast effort to bring a modern operating system to legacy hardware.
