'''Windows 8 build 8412''' is an unleaked pre-RTM build of [[Windows 8]]. A screenshot of its [[Windows 预安装环境|Preinstallation Environment]] running an automated deployment script was found on the contents of an HP Pavilion TPN-Q112{{efn|Unreleased device.}} development machine, which ran a copy of [[Windows 8 Build 8419.0.winmain.120521-1835|build 8419]].<ref>https://www.betaworld.cn/Windows_RT:6.2.8412.0.winmain.120507-1805</ref> Multiple log files in the publicly available dump of said build in the <code>SYSTEM.SAV\Logs\</code> directory, along with said screenshots. Additionally, Three screenshots of the CoreARM version were uploaded to the website BetaUnleaked on 6 August 2023, although they cannot be confirmed or refuted at this time.<ref>https://betaunleaked.wixsite.com/blog/post/windows-rt-8412</ref> Images of this build's x86 compile in the Pro SKU were found on an eBay listing. Despite the build number being higher than the [[Windows 8 Build 8400.0.winmain_win8rc.120518-1423|official Release Preview]], it was compiled eleven days earlier.

This build is notable for having the hash removed from the watermark, in a similar case to [[Windows 8 Build 8375.0.winmain_win8rc.120504-1900|build 8375]], however the hash is now present in the [[winver]] dialog.
