Windows 10 Build 14393 and 14931 Now Available as ISO Downloads

For the first time since beginning the development of Redstone 2, the next major update to Windows 10 which is expected in early 2017, Microsoft has moved one of the Fast Ring Insider builds to Slow Ring testers.

Dona Sarkar, head of the Windows Insider Program at Microsoft, announced the availability of Windows 10 Build 14931 for the Slow Ring via Twitter and that began a process which made the ISO image of that build available for download.

However, alongside of Build 14931 Microsoft has also made Windows 10 Build 14393 available for download.

If this build sounds familiar it is the base build for the Windows 10 Anniversary Update that was released on 02 August with KB3176929 that brought the Anniversary Update release to OS Build 14393.10.

If you want to download either one of these builds all you need to do is visit and log in with your Microsoft account which is associated with your Insider account.
