Windows Phone 8.1 build 12400.899.WPMAIN 是 Windows Phone 8.1 官方开发者预览版的第四个更新暨 Windows Phone 8.1 的正式版本之一， 也是后续大规模向多个国家和地区的多数 Lumia 品牌和非 Lumia 品牌的运行 [[OS:Windows Phone 8|Windows Phone 8 手机操作系统]]的设备所推送的 Windows Phone 8.1 正式版之一。
与携带 Delta 增量包的 [[OS:Windows Phone 8/8.00.10532.166.WP8_CXE_GDR3(wpbldlab).20140321-2120|Windows Phone 8 build 10532.166.WP8_CXE_GDR3]] 和 [[OS:Windows Phone 8.1/8.10.12397.895.WPMAIN(wpbldlab).20140530-2215|Windows Phone 8.1 build 12397.895.WPMAIN]] 一同发布至 [[Windows Update|Windows 更新]]服务器上并提供下载及安装。<ref>[https://github.com/Empyreal96/WPCabLinks.db/tree/main/8.10.12400.899%20(WPMAIN(wpbldlab).20140709-1912) WPCabLinks.db/8.10.12400.899 (WPMAIN(wpbldlab).20140709-1912) at main · Empyreal96/WPCabLinks.db · GitHub]</ref>
本站用户 YZ22B338807 所购买的一台二手诺基亚 Lumia 920 手机运行此系统， 其 “附加信息” 页面所显示的固件名称为 “Lumia Black” （现实中 Lumia 机型对应的 Windows Phone 8.1 正式版公开固件名称应为 “Lumia Cyan”）， 故推测当年可能是从 Windows Phone 8 更新至 Windows Phone 8.1 时会升级到此系统。
2014 年 7 月 16 日推送给加入 “用于开发人员的预览” 计划的 Windows Phone 设备用户及开发人员。<ref>[https://livesino.net/archives/7228.live Windows Phone 8.1 开发者预览版新版本推送 | LiveSino 中文版 - 微软信仰中心]</ref><ref>[https://www.windowscentral.com/microsoft-releasing-build-12400-windows-phone-81 Microsoft is now releasing build 12400 of the Windows Phone 8.1 OS preview | Windows Central]</ref>
