    Windows Update for Business and the retirement of SAC-T in Windows 10


    Last Updated: 31 May 2020 at 08:59

    Update 7/15/2019: As a reminder to customers on Windows 10, version 1809 using Windows Update for Business with a Branch Readiness Level set to Semi-Annual Channel and a default 0-day deferral, your 60-day one-time built-in deferral period will end on Tuesday, July 23, 2019 and your devices will begin updating to Windows 10, version 1903.

    Update 2/28/2019: This change does not affect SAC-T for Office 365 ProPlus customers. See below for details.


    In my post last May on Windows 10 and the “disappearing” SAC-T,I explained how we simplified and aligned our Windows servicing terminology with Office, reflecting that there are two Semi-Annual Channel (SAC) releases each year. I also explained that with Windows, there was never actually a Semi-Annual Channel (Targeted), or SAC-T, release; rather, SAC-T merely reflected a milestone for the semi-annual release. Unless you were using Windows Update for Business, the SAC and SAC-T designations had no impact on when your devices would be updated. At the time, we had not yet completed the work necessary to deliver the changes needed for Windows Update for Business to reflect the alignment with Office so we continued to show dates for both the SAC and SAC-T milestones on the Windows 10 release information page.

    We have now completed that work. Beginning with Windows 10, version 1903 (the next feature update for Windows 10), the Windows 10 release information page will no longer list SAC-T information for version 1903 and future feature updates. Instead, you will find a single entry for each new SAC release. In addition, if you are using Windows Update for Business, you will see new UI and behavior to reflect that there is only one release date for each SAC release. If you use System Center Configuration Manager, Windows Server Update Services (WSUS), or other management tools, there will now only be one feature update published to WSUS, and this will occur at the time of release.

    With this upcoming change, Windows Update for Business customers may have a few questions and I’ll try to address those now. To restate what I said above, unless you are using Windows Update for Business, the changes discussed below have no impact on when your devices get updated.

    With the release of Windows 10, version 1903, how will my Windows Update for Business configuration and execution reflect the removal of SAC-T?

    For releases prior to version 1903, Windows Update for Business customers had two settings they could utilize to designate when feature updates should be installed on their devices. The first was the branch readiness level (SAC or SAC-T), and the second was the deferral period, which specified the number of days after the branch readiness level-based date before an update was offered to a device.

    Once your organization’s devices have been updated to Windows 10, version 1903, the configuration of Windows Update for Business will be simpler, enabling you to choose a single deferral value based solely on the SAC release date. That means, if you are trying to set up validation flights in your environment using Windows Update for Business, or stage updates in waves, you will do so from a common release start date, which should simplify the deployment process overall.

    I want to clarify; with these changes, we will not change your deferral value. Instead, it will remain as it was configured following the update to version 1903. In addition, while all Windows Update for Business device deferrals will now be based on the release date (you will no longer have to configure this), you will continue to have the option to enroll devices in the Windows Insider Program and choose a pre-release ring, such as Slow, Fast, or Release Preview.

    How to Defer Feature and Quality Updates in Windows 10

    The image below shows the Settings panel as it looks today with Windows 10, version 1809.



    When version 1903 is released, it will look like this:



    As you can see, it shows only pause and deferral settings; Semi-Annual Channel (Targeted) is no longer presented as an option. Again, this change will only be seen once you have deployed Windows 10, version 1903 and will only impact future feature updates after version 1903. Devices enrolled in the Windows Insider Program; however, can already see these changes.

    How is Microsoft going to handle the transition to Windows 10, version 1903 for customers who have their branch readiness level configured for SAC?

    As I said above, with version 1903, we will cease to publish both SAC and SAC-T dates. Each release will have a single SAC release date so we will handle this one-time transition in the following manner:

    • Windows Update for Business customers who have configured a deferral based on the SAC-T branch-readiness level (remember, this really is the actual release date), devices will be offered the update once the configured number of deferral days have passed. Thus, no change from previous releases.
    • For devices that have been configured with a branch readiness of SAC, for the upgrade to version 1903 only, we will add an additional 60 days to the configured deferral. This will simulate the delay previously experienced when Microsoft declared the SAC milestone. For example, if your device is currently configured to defer updates 30 days from the SAC release date, for the upgrade to version 1903 (and this time only), we would append a 60-day delay to that configured 30-day deferral–meaning that the device would be upgraded 90 days (60+30) after version 1903 is released. (Note that the additional 60 days will be handled on our service side, and will not be reflected in your device configuration.)
    • For subsequent feature updates after version 1903, your Windows Update for Business configuration deferral value will be whatever it was before version 1903; we are not modifying that value.

    For future upgrades beyond Windows 10, version 1903, to establish an additional delay and recreate your deployments rings on the schedule you want, you will need to update your deferral value. Using the same example above, you would change the deferral value from 30 to 90 days. Or, if you want to create a three-ring deployment model, you could have three groups of devices, designated simply with deferral values from the single release date, perhaps 30, 60, and 90 days.

    Let me see, if I've got this right....

    Quote from the OP:

    For devices that have been configured with a branch readiness of SAC, for the upgrade to version 1903 only, we will add an additional 60 days to the configured deferral.

    The current SAC (1809) defers feature update for four month, quote from group policy:

    * Semi-Annual Channel: Feature updates will arrive when they are declared Semi-Annual Channel. This usually occurs about 4 months after Semi-Annual Channel (Targeted), indicating that Microsoft, Independent Software Vendors (ISVs), partners and customer believe that the release is ready for broad deployment

    Is MS going to add 60 more days to the 120 days (4 month) after the 1903 update applied? That effectively would result in 180 days feature update deferral.

    If MS will disregard the current SAC value, will the 1903 set the deferral to at least 60 days? If MS does not do that, that would effectively make the "Windows Update for Business" the same as the current SAC-T. That would be bad, if and when 1909 comes out...

    Since MS will pretty much control the feature update deferral for "Windows Update for Business" after 1903, does that mean the relevant group policy settings will have no impact to defer feature updates?

    Just in case, my system is set to SAC with 120 days deferral. If MS statements are correct, the end result of the 1903 update deferral should be 180 days. We will see...

    No; the 60 days is instead of the 120. And it's before/for the 1903 update, not after.

    Just once, for the update to 1903.

    Yes, the SAC cushion is eliminated after 1903; deferring by 1 to 365 days would then be the only delay available.

    Deferral by 1 to 365 days remains as before; only the branch/channel selection difference is eliminated.

    180 for the update to 1903, but back to 120 for update to 1909 and beyond.
