Microsoft today released Windows 10 Build 10122 to fast ring customers. Since this release is for fast ring customers, Microsoft didn’t release any official ISOs to download. However, you can create your own ISO using the following ESD files. Both of them are English language builds.
If you don’t have time for that, you can download it from the torrents. The ISO file was from the ESD file downloaded from Microsoft.
Will update links to other builds as they are online.
Thanks to Ludacris for sharing the build.
