Microsoft published Office and Windows servicing and support changes

In last Decembers post I told you about Windows 10 1511 extended support. Now some days ago Microsoft published a blog article on additional information about their Office and Windows servicing and support changes. Let’s have a closer look at the dates and requirements mentioned in the post on the Microsoft blog. Please find the original post here.

Before we review the support lifecycle, let me emphasize that Microsoft once again provides an extended lifetime support which exceeds the "end of support" lifetime. On the same view I recommend you to not use long-term service branch versions of Windows 10 on a Desktop or Laptop computer (not a machine controller / production device), as you may run into additional trouble the the "end of support" boundary with your hardware / driver support.

With that said let’s have a look at the support lifetime table as published by Microsoft

There is an additional statement which should be notified: “To clarify our current support practices for ProPlus running on Windows 10, ProPlus will not be supported on Windows 10 Semi-Annual Channel (SAC) versions that are no longer being serviced.“, so even an Office version which is in support stops beeing supported when running on a Windows 10 build which is not supported.

Microsoft goes even further with “Effective January 14, 2020, ProPlus will no longer be supported on the following versions of Windows. ” […] “Any Windows 10 LTSC release“. Here’s something to note – any version is also related to Windows 10 LTSB 2018! This LTSB is mentioned to be supported by running the Office 2019 perpetual version, while it will not support running ProPlus for now.

That may lead to additional dependencies.
