Windows Polaris OS build 16299

Windows Polaris build 16299.241 is the only leaked build of Polaris as of 2021. It was leaked on 2 January 2021in the ARM (ARM32) architecture. This build contains nearly nothing in terms on user experience, only containing a fallback UI that is just the Windows logo in a different shade of color. The only thing doable at that point is to shut down the device it's running on or potentially open a command prompt over a computer with a USB connection.
