Evidence has been mounting lately to indicate that Windows 10 build 15063 is the 'RTM' build for the upcoming Creators Update, also referred to as 'Version 1703'. That build is now available for PCs and phones in the Fast ring, PCs in the Slow ring, and for those on the Xbox Insider Program; and the SDK and Mobile Emulator for the same build appeared online last week.
On top of that, Microsoft has released its first preview of Version 1704 for Xbox Insiders, which is also part of the build 15063 series - another strong indicator that 15063 will be the build that is rolled out globally to devices as the Creators Update in the weeks ahead.
Microsoft hasn't yet made an official announcement about whether or not 15063 will be the 'final' Creators Update build for that rollout - and it's possible that such an announcement may never come. But with very little time remaining until the update's release, it's looking increasingly likely that that will be the build (although the final release may well include some sort of cumulative update with additional bug fixes, and a 15063.xxxx build number).
Today, ISOs for build 15063 have made an appearance on Microsoft's servers ahead of their official release. Steve Truman (@KPRP42) shared the direct download links with us for two of the build 15063 ISOs that are now available from Microsoft.com:
- Windows10_InsiderPreview_Client_x64_en-us_15063.iso (64-bit PC)
- Windows10_InsiderPreview_Client_x32_en-us_15063.iso (32-bit PC)
We've installed build 15063 using the ISOs on two systems, with no issues during installation. As you can see from the links above, they still identify the build as an 'Insider Preview'; the app no longer displays 'Insider Preview' in Settings > System > About, but since this has been the case in other recent preview builds, this should not be taken as implicit confirmation that 15063 is the RTM build.
With the ISOs now on Microsoft's servers, an announcement about their availability should come soon, and that they'll be posted to the official Insider Preview download page in the coming days along with Enterprise, Education, and other variants.
Update: 18 hours after the ISOs appeared on Microsoft's servers, it seems they've now been pulled, returning 404 errors when trying to download. It's likely that they'll return eventually as the 'final' RTM release - including the additional 15063.xxxx cumulative updates that will eventually roll out as the Creators Update. For now, it appears that build 15063 won't be available for a little white so hang in there for now!
