After years of trying to get Windows 10 Mobile off the ground, Microsoft has announced they are calling time on the platform. The company has updated a support page on their site, outlining when support for the platform will end. Officially, that is December 10, 2019.
As of December 10, 2019, Windows 10 Mobile users are no longer eligible to receive new security updates, non-security hotfixes, free assisted support options, or online technical content updates from Microsoft for free. Third parties or paid support programs may provide ongoing support, but it is important to recognize that Microsoft support will not publicly provide updates or patches for Windows 10 Mobile.https://support.microsoft.com/en-us/help/4485197/windows-10-mobile-end-of-support-faq
Only device models that are eligible for Windows 10 Mobile, version 1709 are supported through the end date. For Lumia 640 and 640 XL phone models, Window 10 Mobile version 1703 was the last supported OS version and will reach end of support on June 11th, 2019. Please see the Windows 10 Mobile availability per device model for more information.
The news is certainly not surprising. Microsoft has had multiple failed attempts to get a mobile version of Windows off the ground with limited success. Part of this has been due to the lack of consistent upgrade paths from one version to another which was seemingly going to be addressed with Windows 10. However it never fully came to bare. By the time the platform was available, Both Apple with iOS and Google with Android were in such dominant positions that Microsoft had little chance for success.
As for what customers are to do, Microsoft has been pretty frank: Go get an iPhone or an Android phone. The company has shifted its mobile strategy to apps, notably the Office 365 suite of apps along with others. This is the Redmond, Washington company’s long term mobile strategy where they will be able to leverage the two dominant platforms out there in iOS and Android.
As a long time Windows 10 Mobile supporter and one who was a Microsoft MVP for many years for the platform, personally it is a sad day for me but not one that is shocking.
