Windows 10 Mobile OTA update is now officially available and Microsoft has announced the initial list of smartphones running on Windows Phone 8.1 OS that will receive the first wave of the update. It also released a how-to video to assist users to upgrade to the latest operating system.

Microsoft had been delaying the arrival of Windows 10 Mobile update since December last year. Earlier this month, several carrier partners like Vodafone Australia, Vodafone Italy and T-Mobile Croatia said the update would be available this month, and now, it has finally been released.

Windows 10 Mobile – Eligible Devices

The Windows 10 Mobile update brings several new features like the Microsoft Edge browser, Cortana voice-assistant, and Continuum, as well as various performance enhancements. The official Microsoft blog confirmed that the following Windows Phone 8.1 devices will start receiving the Windows 10 Mobile OTA update from today:

  • Lumia 1520
  • Lumia 930
  • Lumia 640
  • Lumia 640XL
  • Lumia 730

Incompatible Devices

Microsoft also said: "many older devices are not able to successfully upgrade without an impact on the customer experience.” Hence, some popular Windows Phone 8.1 devices like Lumia 1020, Lumia 920, Lumia 630 and Lumia 530 are not included the above list, primarily because Windows 10 Mobile is unable to run smoothly on these devices. These smartphones may be included in the second set of eligible devices.

How to Upgrade to Windows 10 Mobile

Owners of Windows Phone 8.1 devices are required to download and install the Upgrade Advisor that is available on the Windows Store. Once installed, it will check whether the phone can be upgraded to Windows 10 Mobile.

After selecting ‘Enable Windows 10 upgrade,’ the app will check for available disk space for the upgrade. It will allow users to temporarily back up their files to a location of their choice, an SD card, OneDrive or a customized location.

Next, users can navigate to Settings > Phone update to check for Windows 10 Mobile update. It will become available for installation after the OS update gets downloaded to the device. After Windows 10 Mobile is successfully installed, users can restore the backed up file easily.
