Calculating Semi-Annual Channel (Broad) Milestones

[Kurt Mackie]

How will organizations calculate semi-annual channel (broad) milestones, the formerly known "current branch for business" deployment milestones for Windows 10? 

We've heard previously from Microsoft that organizations have 18 months before they have to perform an upgrade or lose security patch support, but that's based on the "monthly channel" milestone (formerly known as the "current branch"). So do organizations actually have 14 months between semi-annual channel (broad) milestones? Is it a fixed span now? How will organizations understand how much time they have to move?

Hello

I asked the same question in French MPN yammer, and the following milestones have been validated :

a) T0 : Sept 2017 : Windows 10 1709 released in Pilot version (ex-CB)
b) T0 + 4 month   : Jan 2018, 1709 status moves to Broad (ex CBB) for 12 month
c) T0 + 16 month  : Jan 2019, 1709 moves to Grace delay for 60 days (2 month)
d) T0 + 18 month  : Mars 2019, 1709 End Of Life.

Note than from Sept 2017, the same milestones apply to SCCM ;)

Semi-Annual Channel releases are serviced for 18 months from the date of release.  So for example, Windows 10 1703 was released on April 11th; it will be serviced through October 2018.  We expect to start publishing these dates on the http://aka.ms/win10releaseinfo page (ideally on the date we release) in the near future.

Note that this isn't really a change from before.  We used to say that we have "two CBB releases supported at all times, plus a 60-day grace period."  But with regular every-six-month releases, that math equation always works out the same:  18 months from the date of release.  So we've just simplified the message.

in which way does the release date in select portal for Enterprise licenses have effect on this schedule.

These are release dates for Enterprise?

Does the 18 month cycle for enterprise start with release date of windows 10 enterprise?

Hello

The unique release date is mentionned in the the column "Availability date" (or "Verfügbarkeitsdatum" if i have a good reading of your URL).

This T0 date is the start date for the 18 month cycle :

T0 : Availability date of a Version, start of Pilot status

T0 + 4 month : end of Pilot status, start of Broad status

T0 + 16 month : end of Broad status, start of Grace Delay

T0 + 18 month : end of Grace Delay, End of Life of the Version.

There is no particular date for W10 Enterprise vs W10 Profesional.
