Windows 8 build 8412 is an unconfirmed pre-RTM build of Windows 8. A screenshot of its Preinstallation Environment running an automated deployment script was allegedly found on the contents of an HP Pavilion TPN-Q112 development machine, which ran a copy of build 8419,[1] and three screenshots of the CoreARM version were uploaded to the website BetaUnleaked on 6 August 2023.[2] Despite the build number being higher than the official Release Preview, it was compiled 11 days earlier, in a similar fashion to build 8277.
