Segoe UI
As of 2021, it is the earliest shared build to use the new version of the Segoe UI font that would be used in later builds through to the final version.

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.
