Microsoft has launched a phased process for automatically distributing the Windows 10 November 2019 Update (version 1909) for devices running older versions of the OS, including the October 2018 Update.
As Microsoft points out, automatic (forced) updates help ensure that users are using current, maintained versions of Windows 10.
The October 2018 Update (version 1809) was released last fall, and its support will be completed on May 21, 2020.
On December 5, on a Windows 10 Health Dashboard information page, the company announced:
Starting today, we are gradually launching a phased process for automatically distributing feature updates for devices running Windows 10 October 2018 Update (version 1809) of the Home and Pro editions so that these devices continue to receive monthly updates and critical security patches necessary to maintain a healthy ecosystem . The forced update begins a few months before the end of the service to ensure the smoothest transition to the new version.
Microsoft emphasizes that starting the upgrade process early ensures that users have enough time to upgrade systems before completing their support. The company assured that this time no aggressive tactics will be applied – users will have a lot of time to upgrade devices to the Windows 10 November 2019 Update (version 1909).
Microsoft already took a similar approach a couple of months ago when it launched a forced update of the Windows 10 April 2018 Update (version 1803) to the May 2019 Update (version 1903). You can disable the automatic update of Windows 10 to prevent upgrading to a new version, but keep in mind that in this case the system may remain vulnerable to malware and exploits.
