Windows 8 build 8133 (fbl grfx dev1)

Windows 8 build 8133 (fbl_grfx_dev1) is a build of Windows 8, which was uploaded to BetaArchive on 31 December 2019.

Segoe UI
It is currently the earliest available build to feature an updated Segoe UI font, bringing over much of the typography changes intended for the Segoe WP typeface (which was largely used throughout the Windows Phone operating system family).

Installation
It is the first build in which the boot spinner replaces the progress bar during the second and third phase of installation.

Hardware compatibility
It is recommended to set the hardware compatibility to version 9.x on VMware, otherwise booting from setup will result in a garbled black screen.
