Windows 11 build 25267 (rs_wdatp_edr) is an internal build of Zinc, which was released to Microsoft Collaborate partners participating in the Microsoft Defender for Endpoint program on 17 December 2022. The build eventually leaked and was shared to the public on 26 March 2023 in the form of a bootable Hyper-V Generation 1 virtual hard disk image, nearly two years since the leak of Cobalt build 21996, which was the previous occasion from when an internal build from an ongoing milestone had been disclosed to the public.
As the build itself comes from a development branch intended for Microsoft Defender's Advanced Threat Protection functionalities, namely as it pertains to the built-in enterprise-specific Endpoint Detection and Response utilities,Raya, Thomas et al. Overview of endpoint detection and response, Microsoft Learn. 18 December 2020. it notably includes several features that were either not included by default in public branches until they were later rolled out to Windows Insiders or are reserved for internal Microsoft use, including an internal "Experimental Features" drop-down menu that is part of the Settings application.
== New features and changes ==
=== Windows Spotlight ===
The new Windows Spotlight user interface, initially implemented in build 25197 and later removed in build 25206, has been re-implemented with multiple refined visuals. This feature is only available in the English (United States) language, and can be toggled on manually by enabling Velocity staging keys 39880030 and 40268500 (with the variant parameter set to 0, 1 or 3 for multiple visuals).
=== System-wide Dark Theme ===
A work in progress version of a System-wide Dark Theme has been added. It looks very incomplete with certain dialogs not having the dark theme and a few others like property sheets in File Explorer looking unfinished. This feature needs to be enabled manually by enabling Velocity staging key 26338762.
