The next Windows 10 Long Term Servicing Channel (LTSC) release

Hi Joe_Lurie 

Please clarify the mainstream and extended support dates for the client LTSC. Microsoft provides conflicting information as of today.

In this blog post you state

Windows 10 Client LTSC will change to a 5-year lifecycle

Are you talking about the mainstream support, extended support, or the total? The word change makes sense only in the context of the total, because LTSC 1809 has 5 years of mainstream and 5 years of extended support.

This page https://docs.microsoft.com/en-us/windows/whats-new/ltsc/whats-new-windows-10-2021  says the same thing without clarifying the support type.

But this page http://aka.ms/win10releaseinfo lists 5 years of mainstream and 5 years of extended support for LTSC 21H2 (2021), the total of 10 years. This is what's posted as of today

What have you changed then?

Digging into this a bit deeper, we can compare the lifecycle pages

https://docs.microsoft.com/en-us/lifecycle/products/windows-10-enterprise-ltsc-2021 

vs

https://docs.microsoft.com/en-us/lifecycle/products/windows-10-enterprise-ltsc-2019

The difference is that LTSC 2021 does not have the extended support. If that's the case, why wouldn't you have said that straight?

But then http://aka.ms/win10releaseinfo is wrong.

Thanks.
