At long last, Microsoft has finally explained what happened with the accidental release of the internal build 19847 to all Windows Insiders. According to the company, the build was “accidentally released to a very limited number of Windows Insiders,” which is surprising as it’s been confirmed that even Insiders on the Release Preview Ring have been seeing it in Windows Update.
Earlier today, Build 18947 was accidentally released to a very limited number of #WindowsInsiders. Insiders should no longer be receiving this build. If you received this build – please read this forum post for details https://t.co/dDmdWJ1Zb0.

Anyway, the build 19847 has now been pulled and Jason Howard from the Windows Insider team shared the following explanation for this snafu, promising that Microsoft has made the necessary changes to prevent this from happening ever again:
Windows Insiders may be wondering what caused this scenario. We actively test and validate each of our preview builds internally before sharing them externally, however a configuration change allowed this build to release to multiple rings simultaneously, including external rings. We have made the necessary remediation in our flighting service and have implemented additional changes to help prevent from this happening in the future. We apologize for any troubles this may have caused for affected Insiders and appreciate your assistance in bringing this to our attention so we could make the necessary changes as quickly as possible.
In case you installed the build 19847 by mistake on your PC, Microsoft invites you to roll back to the previous build from the Settings app (you can learn more details about how to do it on the forum post). So far, it seems that the build 19847 doesn’t have any major issues, but it includes interesting changes such as a redesigned Start Menu with no Live Tiles, as well as a new layout for Control Center. It’s possible that this internal build hides more new features that Microsoft could officially reveal in the coming weeks, but Microsoft is really inviting users to roll back to their previous build as this “will put you back into the proper state.”
Microsoft was surprisingly slow to officially acknowledge the issue and explain what happened today, but we’re glad the company finally did it. There are now more than 15 million Windows Insiders worldwide, and it’s safe to say that many of them have been waiting all day to get a proper explanation. It’s been quite weird to have to wait so long to finally get it, especially when Microsoft is much quicker to communicate about problems affecting Azure, Office 365, or Xbox Live.
Anyway, we hope this has been a learning experience for the Windows Insider team, and we can’t wait for things to get back to normal. All in all, we know now that there are some interesting design changes coming to Windows 10 in the near future.
