Windows 8.1 build 9374 has leaked unto the web.
All over the web, you can find links to the build 9374 of Windows 8.1.
We won’t be linking to any of these developmental (illegal) builds and highly caution you against downloading those to any PC that you even remotely care about.
These early builds are breeding grounds for viruses and malware so be careful out there. The real thing is coming soon anyway.
