Windows 10 Mobile was a dead platform a few years ago, with a market share of less than 1%. Since the release of the 1709 version in 2017, there has been no update. At the end of last year, Microsoft announced that it would officially stop supporting Windows 10 Mobile on December 10, 2019.
At present, this date has arrived. However, Microsoft added that Office applications on phones that load Windows 10 Mobile, including Word, Excel, PowerPoint, and OneNote, will be extended until January 12, 2021. At that time, these applications will no longer receive Microsoft security updates, non-security fixes, free secondary support, or online technical content updates.
Microsoft also said it would continue to strongly support Office applications on iOS and Android, and strongly recommended that users of Windows Mobile transition to iOS or Android as soon as possible.
In addition, the Windows Phone 8.1 Store is officially closed today, December 16, 2019. Lumia phones that use Windows Phone 8.1 will continue to work after this date, but cannot download, install, and receive updates.
Windows Phone is already small, and Windows 10 Mobile also failed. In October, the launch of the Surface Duo smartphone signalled that Microsoft had apparently not given up on the mobile space, but the two-screen folding phone was running Android, and it seems Microsoft’s attempt at Windows on the mobile platform will not make a comeback any time soon.
