For developers and enthusiasts who want to test Build 15035 without dedicated ARM hardware, QEMU emulation is a viable option.
With the device now reset and BitLocker removed, you can proceed with the main installation.
The process utilizes automated tools developed within the Open Surface RT and XDA developer communities. You must source the following components to configure the build environment:
Some leaks include a BuildMedia.cmd script: windows 10 build 15035 media builder install
Note for ARM/Surface RT users: You may need to open the command prompt (Shift+F10) and use diskpart to format the installation partition to NTFS. 4. Post-Installation (ARM Specifics)
The Media Builder tool is a utility provided by Microsoft that allows users to create installation media for Windows 10. This tool can be used to create a bootable USB drive or ISO file that can be used to install Windows 10 on a new device or to upgrade an existing installation.
Ensure you have a file named desktopdeployment.cab or windows10.0-kb1234567-x64.cab . Without these, the build will fail. For developers and enthusiasts who want to test
The process began in earnest. The UI was sparse, offering no percentage points, only the phrase: Creating Windows 10 media .

Before investing time, remember that this build is a buggy, obsolete pre-release version not intended for everyday use. It offers a glimpse into Windows development history, but it will not provide a stable or practical computing experience. If you understand these risks and are prepared for a complex, multi-step process, however, the resources exist to let you explore this unique piece of Windows history on your own terms. You must source the following components to configure
: Supported, but requires a strict Secure Boot disabling procedure.
: This is strictly an experimental hobbyist project. The build is officially unsupported, suffers from performance degradation due to the 2GB RAM limits of legacy tablets, contains inherent bugs, and lacks modern Prism emulation layer compatibility for running standard x86 applications.
