The build includes a subset of minor fit-and-finish changes that continue to reflect the intended vision for the Metro design language introduced as part of the operating system, and is notably one of the last few builds to incorporate the older Windows flag logo introduced in 2001 (as part of Windows XP's release), along with builds 8195 and 8277, as the official Consumer Preview build would eventually introduce the 2012-2021 flag design. | The build includes a subset of minor fit-and-finish changes that continue to reflect the intended vision for the Metro design language introduced as part of the operating system, and is notably one of the last few builds to incorporate the older Windows flag logo introduced in 2001 (as part of [[Windows XP]]'s release), along with builds [[Windows 8 Build 8195.0.fbl_dnt3_wireless.120201-1800|8195]] and [[Windows 8 Build 8277.0.fbl_dnt2_bus.120208-1700|8277]], as the official Consumer Preview build would eventually introduce the 2012-2021 flag design. | ||
As the build comes from a [[内部版本实验室|public release branch]] intended for the official Consumer Preview release, several anti-leak mechanisms have been relaxed. | |||

The Boot Graphics Library has been updated to accommodate for legacy BIOS machines utilizing a widescreen monitor configuration; the boot screen, system crash screen and the second stage of setup therefore utilize 16:9 aspect ratio variants of the logo bitmap and Segoe Boot font face, with resources designated under the N moniker. | The Boot Graphics Library has been updated to accommodate for legacy BIOS machines utilizing a widescreen monitor configuration; the [[启动屏幕|boot screen]], system crash screen and the second stage of setup therefore utilize 16:9 aspect ratio variants of the logo bitmap and Segoe Boot font face, with resources designated under the <code>N</code> moniker. | ||

* The <code>CanUpdate</code> element is used here; the code using it was removed later but the element remained in the file format.

* Registry rules are not used for low-level cryptographic settings as in later builds but instead are used to override registry values anywhere in <code>HKLM\SYSTEM</code>. The operating system loader <code>winload.e*</code> and NT kernel both have code implementing this functionality; the former uses the policy to override the registry values it reads from that hive. | * Registry rules are not used for low-level cryptographic settings as in later builds but instead are used to override registry values anywhere in <code>HKLM\SYSTEM</code>.

* The shell may attempt to invoke a Windows Explorer window that navigates to an unoccupied drive letter before an ISO image is able to finish mounting, in turn displaying an invalid path error.
