The devices that powered the Surface RT and Surface 2 lines use the NVIDIA Tegra 3 and Tegra 4 (ARMv7) chips, respectively. Modern versions of Windows, including most builds of Windows 10 and all versions of Windows 11, are compiled for x86, x64, or ARM64 architectures. This means Microsoft never released an official version of Windows 10 that could run natively on these devices. Build 15035, therefore, was a significant leak, offering a glimmer of hope for those wanting to upgrade.
