We get emails asking us this question at least once a day and we understand the frustration. Microsoft hasn't been clear on when Windows 10 Mobile will be released for those of you who own a Windows Phone 8.1 device. If you are not an avid reader of our site (you should be!), you're likely scouring the internet, shuffling past all the publications, looking for an answer. We'll, here's the latest and we'll let you know if anything changes.
This November we introduced Windows 10 to phones including brand new features such as Continuum and Universal Windows Apps with the introduction of the Lumia 950 and 950 XL. The Windows 10 Mobile upgrade will begin rolling out early next year to select existing Windows 8 and 8.1 phones.
Windows 10 Mobile will be rolled out to existing Windows Phone 8 and Windows Phone 8.1 devices "early next year." Microsoft is not specifying exactly which devices will receive the update, or if it will be rolled out in phases. Windows 10 Mobile was finalized in November of 2015 and originally we expected it to be released in December, but that obviously didn't happen. Let's hope Microsoft's "early next year" promise doesn't change either.
