Windows 8 build 8318

Windows 8 build 8318 is an unleaked build of Windows 8. This build was first shown running on a Samsung Series 5 tablet/notebook convertible at Computex 2012. The ARM32 version of this build, which likely originates from a Surface RT engineering sample, was supposedly uploaded to the Chinese website BetaWorld on 30 September 2019, although this cannot be confirmed or refuted as the build is not publicly available.

Changes
The button controls in the Windows Aero visual style were updated to feature a flat design that is largely consistent with the Metro design language.
