Quote:It appears that Microsoft plans to increase the adoption of Windows 10 version 1809, the October 2018 Update, in the last week of December and going forward.

Eagle-eyed users over on Ask Woddy noticed that Microsoft updated KB4023814 recently. KB4023814 -- Some versions of Windows 10 display a notification to install the latest version -- describes how the Windows 10 Update Assistant may be launched on devices running earlier versions of Microsoft's operating system to prompt users to upgrade to the new version.

Microsoft enabled updates to the new feature update for Windows 10 already for users who click on the "check for updates" button in Windows Update or use other feature updates upgrading methods.

KB4023814 suggests that Windows 10 users may get upgrade prompts automatically without them doing anything update related. In other words: the following prompt may be displayed on Windows 10 devices running pre-1809 versions of the operating system (note that the screenshot shows 1803, but that is because Microsoft has not updated it yet) even if an administrator does not check for updates manually.
