Windows 8.1 build 9271

Windows 8.1 build 9271 is the earliest known and available build of Windows 8.1, which was uploaded on 27 June 2022, alongside builds 7777 and 7779. Due to its earliness, this build still identifies itself as its predecessor and still bears the 6.2 kernel version.

Setup
Setup is similar to Windows 8, except the borders on the fake Aero setup interface are now opaque.

Pre-RTM wallpapers
Despite being newer than the RTM build of Windows 8, it still uses the older wallpapers used in Windows 8 build 8102 to 8195, build 8277 to 8305, build 8432 to 8441, build 8520 and the  branch compile of build 9200's. This is similar to how Windows 8 build 7700 uses the "betta fish" wallpaper seen in many Windows 7 builds. The wallpaper was reverted to the default wallpaper starting in build 9299.

General
The Earth and Flower theme names are swapped.

Windows Defender
Windows Defender does not launch due to error code.
