Microsoft has shipped Patch Tuesday updates for all supported versions of Windows, including Windows 10 Mobile version 1709. The September 2019 cumulative update for Windows 10 Mobile comes without any noticable improvements or fixes.
The update advances the system to Windows 10 Mobile Build 15254.587 (up from 15254.582) and it comes with the following security-related changes:
- Security update to Windows Kernel, Windows Media, Windows Storage and Filesystems, and Windows App Platform and Frameworks.
Windows 10 Mobile Build 15254.587 can be downloaded by checking for updates in the Settings > Update & Security > Phone update. According to support documentation, Windows 10 Mobile will stop receiving the cumulative updates in 2020. The last update could be shipped on December 10, 2019.
The company will stop releasing security and software updates in 2020, and it will also end technical support for the devices on December 10.
Microsoft says Windows Phone users can only create backups for settings and supported apps until March 10, 2020. In 2020, some services will stop working but you will be able to upload and restore photos from backups for some months or one year after Microsoft ends support for the OS in December.
You can keep using Windows Phones after December 10th or you can install Windows 10 ARM. The Redmond firm recommends users to start considering a switch to Android and iOS where Microsoft services are actively supported.
