Microsoft promised Windows Phone users a free upgrade to Windows 10 at its event earlier this week, but it turns out not all phones will be getting the update. Through itsLumia Conversations blog, the company clarifies "not every phone will upgrade or support all possible Windows 10 features," adding that its goal is for "the majority of the Lumia phones running Windows Phone 8 and 8.1" to be upgraded. That's at odds with what the company's Twitter account has said in the past.
