Windows Polaris OS build 16299

Windows Polaris OS build 16299 is the only available build of Windows Polaris OS as of 2023. It was shared on 2 January 2021 under the ARM32 architecture.

This build, identifying itself as "Windows OneCore 10" in the boot manager, contains nearly nothing in terms of user experience, and only features a fallback UI that is merely the graphical mode boot screen. The only thing doable at this point is to shut down the device it is running on or potentially open a command prompt through the Special Administration Console (SAC).
