Last Friday, Microsoft published a post to its Windows for IT Pros blog to announce the transition of Windows 10 Build 1511 to the Current Business Branch (CBB). This means that the dynamics of an update to the CBB are playing out for real, for the first time. Let’s take a look at this post, and try to understand what the impending release of Win10 CBB Update 1 means.
The double entry for DBB will soon give way to a single entry for 1511 only, once new media is released.

What’s Up with Win10 CBB Update 1?
The blog post is entitled “Windows 10 1511 is now a Current Branch for Business (CBB) release” (this is what I’m calling Win10 CBB Update 1 for brevity’s sake). Here’s what it spells out:
- Windows 10 version 1511 feature update (build 10586, released November 2015) has been officially designated with CBB status. This means that organizations can begin deploying that release broadly.
- The code base for the CBB release is something more than just the straight-up 1511 release: it also includes the injection of the March 2016 cumulative update, KB3140768 into that image (this makes sure that businesses don’t run a CBB image subject to known security vulnerabilities that have been patched since the original release date).
- MS will be publishing updated media for the new CBB release through channels that include MSDN, the VLSC, Windows Update, Windows Update for Business, and Windows Server Update Services in the next few weeks.
- For devices configured to “Defer Upgrades,” they will get Win10 1511 as soon as the updated media is published (further deferral delays via policy is not supported for Windows 10 1507).
- Devices receiving updates via Windows Server Update Services, updates to existing Windows 10 1511 features updates must be re-approved once the new updated media is received.
- Those using Windows 10 servicing plans in System Center Configuration Manager will see the update media designated as “business ready.” This causes servicing plans based on that designation to begin to be evaluated.
Those who don’t want to wait for the updated media to be released can create their own by injecting KB3140768 into the original November release media for the 1511 version. See the Windows 10 Release Information page to observe this status change. It looks like the add-package option to the DISM command could make creating your own image for Win10 CBB Update 1 should be fairly easy, too.
