As we discussed in the Windows 10 servicing guidance published on TechNet, each new Windows 10 feature update is initially considered a Current Branch (CB) release, to be used by organizations for initial pilot deployments. The feature update will later be declared as Current Branch for Business (CBB), once we have received feedback and confirmation from organizations, OEMs, and partners, confirming that the feature update is ready for broad deployment.
Today, we are happy to announce that the Windows 10 version 1511 feature update (build 10586), released in November 2015, has been officially declared as Current Branch for Business (CBB), ready for organizations to begin deploying broadly. For most organizations, no specific action is needed as a result of this declaration – you just need to understand the impact of this declaration:
- We will be publishing updated media for Windows 10 1511 in the coming weeks, through various channels including Windows Update, Windows Update for Business, and Windows Server Update Services, as well as on the Volume Licensing Service Center and MSDN.
- The only difference between this updated media and the original Windows 10 1511 release is the addition of the March cumulative update (KB3140768), which has been injected into the installation image.
- If you don’t want to wait for updated media, you can manually inject that same update, or a later one, into an existing Windows 10 1511 installation image.
- For devices already running Windows 10 version 1511, deployed before the CBB declaration, no action is required other than standard monthly servicing. With the installation of the March cumulative update (KB3140768) or any later cumulative update, the device is already running the equivalent of what was declared as CBB.
- If you have devices running Windows 10 1507, you need to understand the impact of the CBB declaration:
- For devices being serviced using Windows Update for Business and configured to “Defer upgrades,” Windows 10 1511 will begin to deploy as soon as the updated media has been published. (Note that the deferral policies that specify an additional number of months to defer the feature update are not supported for devices running Windows 10 1507.)
- For devices being serviced using Windows Server Updates Services, the updates to the existing Windows 10 1511 feature updates will need to be re-approved once the new updated media is received (unless you have an automatic update rule configured for the “Upgrades” category).
- For those using the System Center Configuration Manager Windows 10 servicing plans to keep Windows 10 devices up to date, the updated media will be detected as “business ready,” causing servicing plans based on that “business ready” designation to begin to be evaluated.
- For devices that will be upgraded using System Center Configuration Manager or Microsoft Deployment Toolkit task sequences, you may want to switch to the latest media (downloaded from the Volume Licensing Service Center) instead of the current Windows 10 1511 media. Alternatively, you can inject the March cumulative update (KB3140768) into your existing media.
We have also updated the Release Information page available at https://aka.ms/win10releaseinfo to reflect the updated status of Windows 10 1511.
If you aren’t yet running Windows 10 1511, this would also be a great time to try it out. See https://www.microsoft.com/en-us/WindowsForBusiness/try for more information. And enroll in the Insider Preview program to try out new features that will be coming out this summer in the next Windows 10 Current Branch release.
