Servicing extensions for Windows 10

Windows 10 is being adopted rapidly
by organizations of all sizes, and as customers deploy the product they
are implementing a modern servicing methodology we refer to as Windows as a service.
Many customers – including MARS, Independence Blue Cross, and Accenture
– have made significant progress in moving to Windows as a Service, but
some have requested an extension to the standard 18 months of support
for Windows 10 releases.  To help these customers, we are announcing an
additional six months of servicing for the Enterprise and Education
editions of Windows 10, versions 1607, 1703, and 1709. (Additional
servicing for Windows 10, version 1511 was announced
in November.)  This extension will be offered via normal channels.  The
chart below outlines the impact of these extensions for each of the
last four Windows 10 releases.

Office 2019
Last year at Ignite, we announced Office
2019 – the next perpetual version of Office that includes apps
(including Word, Excel, PowerPoint, and Outlook, and Skype for Business)
and servers (including Exchange, SharePoint, and Skype for Business).
Today we’re pleased to share the following updates:
  • Office 2019 will ship in H2 of 2018. Previews of the new apps and servers will start shipping in the second quarter of 2018.
  • Office 2019 apps will be supported on:
    • Any supported Windows 10 SAC release
    • Windows 10 Enterprise LTSC 2018
    • The next LTSC release of Windows Server
  • The Office 2019 client apps will be
    released with Click-to-Run installation technology only. We will not
    provide MSI as a deployment methodology for Office 2019 clients. We will
    continue to provide MSI for Office Server products.
Office 2019 will provide 5 years of mainstream support and approximately
2 years of extended support. This is an exception to our Fixed
Lifecycle Policy to align with the support period for Office 2016.
Extended support will end 10/14/2025
