How to get the Windows 10 November 2019 Update version 1909

Craig said:

Thanks Bree...i ran the updater to see if there were any new updates available (even though it said i was up to date)...Once it checked, that cumulative update for the previous version disappeared from the optional list

That is the expected behaviour, so it looks like your windows update is working correctly.

What is the size of 1909 windows home iso? What is the size of download via normal WU?

Any info regarding above? I am in metered net. Hence my query.

There is no contest. Go for the upgrade through Windows Update and click 'Download and install now'.


You see, 1909 and 1903 share the same base code and cumulative updates. To upgrade an up to date 1903 machine to 1909 the only thing that will be downloaded is a small enablement package (about 20KB) that turns on the 1909 features and bumps the build number up to 18363. The size of the ISO downloaded by the Media Creation Tool is about 4GB, so it's just as well you won't be needing it.

Windows 10, versions 1903 and 1909 share a common core operating system with an identical set of system files. Therefore, the new features in Windows 10, version 1909 were included in the latest monthly quality update for Windows 10, version 1903 (released October 8, 2019), but are in an inactive and dormant state. These new features will remain dormant until they are turned on through the “enablement package,” a small, quick-to-install “master switch” that activates the Windows 10, version 1909 features.

Thanks Bree.

Thank you for sharing this: I couldn't find this information anywhere. I have a few 1803 systems that need an update and might as well go all the way to 1909.

They'd been set to defer updates: I disabled that on one system and...it started downloading 1809. I about was ready to pull my hair when I realized, "Wait. Let me use the Update Assistant."

Saw it was still the "May 2019 Update" and left confused. Now we know: November 18th, then the Update Assistant will offer 1909 (and save us the 1803 -> 1809 -> 1903 -> 1909 hoops).

If you never click on "Download and install now", will it never be downloaded and installed?

Until 1903 is approaching end of life it will just sit there.

Will it be installed by the following right in this month?
