If you like installing Windows 10 builds for seeing how progress has been made during the development cycle of an OS, an older build of Windows 10 has leaked. Specifically, the build number is 9834 and this leak is from the partner build string.
The leak originated in China and the download weighs in at nearly 5 GB. This build was compiled before the release of the first technical preview which was 9841 and that was released in September.
If this build string sounds familiar, it's because images from this version of Windows 10 leaked back in early September and was the first good look at the OS.
As with any leaked build, we do not recommend installing it. If you choose to do so, it is at your own risk, and there is no support available from Microsoft.
Thanks for the tip Tito!
