All about versions of Windows 10. What is Threshold1, Threshold2 and Redstone
A little over a year ago, I shared my research on versions of Windows 8.1 (and Windows Server 2012 R2). The material caused a heated discussion, which could have been even more if not for the limitations of this blog on the ability to comment on a note to users with a zero rating. So that my note was transferred from Habr to GT, where I myself could not comment on my own article or make changes to it, I missed the point and almost half a year did not add material. Now I want to start collecting new information on Windows 10 builds in the new note, which by some estimates are already three, and four others. I plan to replenish this note with the release of Windows Server 2016 and the Redstone1 build of Windows 10.
To begin with, it should be understood - “Windows 10” is a long time, and this is not one OS, as it was before, but a line that the company will develop over the years. That is, in fact, behind the “Windows 10” tablet, Microsoft changes the OS kernels, offering new versions, like global updates, which are not installed in the usual sense as an addition to the OS, but are put on top of it as a new OS. At the moment, there were two global OS versions - Threshold1 and Threshold2, now Redstone1 is in the process of active testing with a release date at the end of July 2016. There are different assemblies within the global version. The version of the currently installed OS is upgraded by installing updates from Windows Update. Some builds are released as separate images that are available for download and initial installation, but most are simply cumulative updates. Today I will talk about global OS versions and those builds that can be downloaded and installed from scratch.
So, in July 2015, the RTM build of Windows 10 numbered 10240.16384.th1.150709-1700 was assembled. Images of this build 07/29/2015 appeared on MSDN / TechNet / VLSC. It could be downloaded from August using the Media Creation Tool . In the network it is called Threshold1 or "version 1507, 10240".
In September 2015, assembly 10240.16393.th1_refresh.150909-1450 saw the light, which included updates KB3081452 and KB3081455 , which Microsoft distributed as ESD images through the Windows 7 and Windows 8.1 update program to Windows 10 through Windows Update. Rare mentions of this assembly call it Threshold1 Refresh. ESD images of this assembly can still be downloaded from Microsoft and the simple ESD2ISO utility to convert to ISO format.

November 12, 2015 the first global update Threshold2 or “version 1511, 10586” (November 2015) with the build number 10586.0.th2_release.151029-1700 appears on MSDN / TechNet / VLSC. It contains key changes to the Edge browser, Cortana voice assistant and key applications such as Photo, Video, Xbox ONE Assistant. The assembly is available to everyone using the Media Creation Tool .
In February 2016, a large cumulative update KB3135173 was released , which included all the previously released GDR updates for the global version of Threshold2 and the update for KB3135174 for the original global version of Threshold1. The build number for the updated Threshold2 images available from February 9, 2016 is 10586.104.th2_release.160128-1934 (some sources give a different version - 10586.103.th2_release.160126-1819), but I will believe the official statistics available on the Microsoft website . If you did not upgrade to Threshold2, but remained within the global version of Threshold1, then after updating 3135174 your OS version is 10.0.10240.16683.th1.160130-1842.
The February update Threshold2 Refresh, which on MSDN is listed as 10586.104.th2_release.160128-1934, is available via the Media Creation Tool as ESD images, bearing in their name version 10586.0.th2_refresh.160212-2000. I do not know what exactly the joke is in different names, but the files inside the ESD and MSDN images are exactly the same. Winver inside the OS reports version 10.0.10586.104.
At the time of this writing, this is the latest version of Windows 10 available for download as an image, but installing any of the Threshold 2 assemblies and running Windows Update will receive the March cumulative update KB3140768 , which will increase the OS version to 10.0.10586.164. This is a regular update that comes out every month, I will not chase after them in the article; you can see the version on your PC in the HKLM \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ BuildLabEx registry key
The next global update Redstone1 will appear at the end of July 2016 at the same time as Windows Server 2016 is released. Its installation will in fact be an ESD boot image with Windows Update and an upgrade of the current OS. Of course, the version will appear on MSDN / TechNet / VLSC and on Media Creation Tool. I will try to make changes to the note, if the karma is positive, and will not transfer me again to the “read only” mode.
Update: May 23, 2016 Threshold2 Refresh images appear on MSDN (Microsoft calls them Windows 10, Ver. 1511 Updated April 2016) as number 10586.164. Inside there are build files 10.0.10586.162.th2_release_sec.160223-17 28. Although the images were laid out at the end of May, in fact they were collected at the end of February and will fix several critical vulnerabilities that could not be left open in the images. At the time of writing this Update (May 30, 2016), the May cumulative updates are available, increasing the TH2 version to 10586.318 - KB3156421 and TH1 to 10240.16854 - KB3156387
Update: July 18, 2016 the final version of the Redstone1 branch is available for Insider subscribers: 14393.0.rs1_release.160715-1616, within a few days it goes from Slow first to Fast, why in the Release Preview the ring and from August 2 becomes available through Windows Update.
