It is very likely Microsoft started working on builds of Redstone, the codename for the two next big Windows 10 updates expected next year, even before they released build 10586 to the public.
As of today, the foundation for testing Redstone is being laid with the release of Windows 10 Version 1511 (OS Build 11082.1000) to Insiders residing in the Fast Ring for updates.
According to Gabe Aul, in a blog post over at the Windows Experience blog, do not expect a rash of new features or other major changes to the operating system at this point.
Getting this build out now is focused on some other base level elements:
With this build, you won’t see big noticeable changes or new features just yet. Right now, the team is focused on product improvements based on the feedback we’re hearing on the November update to Windows 10. This includes the changes that have also been going out as cumulative updates through Windows Update on your PCs running the Windows 10 November Update...
We’re also working on some structural improvements to OneCore, which is the shared core of Windows across devices. Essentially, OneCore is the heart of Windows, and these improvements to OneCore make building Windows across PC, tablet, phone, IoT, Hololens and Xbox more efficient. We’re doing some code refactoring and other engineering work to make sure OneCore is optimally structured for teams to start checking in new features and improvements in the new year.
Check out those last four words while you are here - in the new year - sounds like this is the last build for Windows 10 Insiders until 2016.
There is also another promise to bump up the pace of fast ring build releases to Insiders but it is also something we have head before. Hopefully, the Windows team is able to make it work this time because it is one of the biggest things Insiders have been clamoring for since day 1 of the program.
Of course, a quicker release pace for builds in the Insider Fast Ring means more bugs so if you have devices enrolled on the Insider Fast Ring now would be the time to move them to slow or remove them from the Insider program completely.
The build update and install took about 30 minutes or so for me and returned an old familiar friend to the desktop - the Insider watermark.
