Microsoft launched its unified platform for all devices under one OS, Windows 10, which generated great amount of interest from its users. After demonstrating the extensive capabilities of Windows 10 Mobile on its flagship Lumia 950, owners of older devices running Windows Phone 8.1 have been eager to know when the new OS will arrive for them.

Microsoft had earlier confirmed that the official OTA rollout for Windows 10 Mobile will begin in December, but a new report suggested otherwise. According to ZDNet's Mary Jo Foley, Windows 10 Mobile will start being rolled out for WP8.1 devices in early 2016.
