Announced Changes to Office and Windows servicing and support – Part 2

In the first post of this series I focused on some of the top Office questions and concerns I was seeing, now it's time to take a closer look at some of the Windows announcements that were included, or more specifically, the Windows 10 Enterprise and Windows 10 Enterprise announcements that were made.

The main part off the announcement was that the abovementioned Windows 10 versions 1511, 1607, 1703 and 1709 will have 24 months of servicing, which gives us this table.

Release Release date End of support End of additional servicing for Enterprise, Education
Windows 10, version 1511 November 10, 2015 October 10, 2017 April 10, 2018
Windows 10, version 1607 August 2, 2016 April 10, 2018 October 9, 2018
Windows 10, version 1703 April 5, 2017 October 9, 2018 April 9, 2019
Windows 10, version 1709 October 17, 2017 April 9, 2019 October 8, 2019

This is an extension of the support announcement from November 2017, and it does not apply to Pro or Consumer SKUs. This also means that it doesn't apply to Windows 10 Business as enabled by Microsoft 365 Business, because it is just a naming change to highlight how it is being managed.

The second major Windows portion of the post was for Windows 10 Enterprise Long Term Servicing Channel (LTSC) 2018, which will be available later in 2018. This includes updated features and new processor support, but doesn't all of the features and functionality of Windows 10 Enterprise Semi-Annual Channel. There is also a crossover Office/Windows component here - If you are planning on running Office 2019 on Windows 10 LTSC it will need to be Windows 10 LTSC 2018, not one of the earlier LTSC releases.

  1. What about Office 2016 support on Windows 10 LTSC 2018? Also, could you clarify more on why Office 2019 support is ending on the same day as Office 2016? Should we expect more products to move into this new lifecycle policy?

    1. Hi – so far this is the information that has been made public, hopefully we will see a few of the outstanding questions answered in future announcements.
