关于对话框

Windows 8.1 build 9477 (fbl_partner_out21) is a build of Windows 8.1. It was uploaded to the Chinese site BetaWorld on 4 May 2019,^[1] and was then shared on the blog of the aforementioned site on 28 October 2024 as a somewhat corrupt raw disk dump of a prototype Lumia 2020 tablet. Prior to its publication, multiple files from this build are present in Windows Andromeda OS build 16266's Data and OSData partitions.

Bugs and quirks

This build cannot be ran by normal means, as due to bitrot in the eMMC this build was dumped from, various files (including the registry) are corrupted. It's required to replace the corrupted registry hives with ones from the ARM32 version of this build's (fbl_partner_out31) compile.
