An old build of Windows Core 'Polaris' has leaked online
An early build of Polaris, a canceled SKU of Windows Core OS, has leaked online. The build is from early 2018, and includes nothing but the bare core OS, meaning there's no composer (shell) or apps present. Windows Core OS is a modern version of Windows that powers HoloLens 2 and the upcoming Windows 10X, and has been in the works for many years.
