Windows 8.1 build 9491 is an unleaked build of Windows 8.1. The Traditional Chinese x86 variant of this build was found on a Samsung XE700T1A prototype, although the contents of the eMMC containing it was completely irrecoverable, save for the main Windows Explorer executable remaining intact.[1][2]

It is notably the last build of Windows 8.1 to be compiled before the jump to build 9600, which was compiled one day after; it therefore serves as the base for the absolute final RTM build.
