As per subject line:
It's official: for all intents and purposes, the Windows Phone era is over. Microsoft has ended support for Windows Phone 8.1 just over 3 years after its April 2014 debut. From now on, your WP8.1-toting device won't get software updates or technical help. This doesn't mark the end of Microsoft's mobile ambitions (Windows 10 Mobile is still hanging around), but it does finish a long, sad story in the company's history that reflects the tech giant's shifting priorities.
