Thats it, smartphones using the penultimate version of the Microsoft OS will finally be able to be upgraded to Windows 10 Mobile, the latest release.

And to do that, we must first ensure that the device is compatible.

Here are the eligible ones: - The Lumia 1520 - Lumia 930 - Lumia 830 - the Lumia 730 and 735 - the Lumia 640 and 640 XL - The Lumia 635 (1 GB), 636 (1 GB) and 638 (1 GB) - the Lumia 532 , 535 and 540- the Lumia 430 and 435 - the smartphone BLU Win HD, Blu Win HD LTE x150q and CJD Madosma Q501.

If the phone is in the list and is running Windows Phone 8.1, you must download the application "Windows 10 Upgrade Advisor App " from the Store and launch it.

Then just keep your smartphone connected to the electrical mains and connect your Wi-Fi or home network to quietly download the update. Once the download is complete, go in the menu "Settings " from your smartphone and select "Update ".

As a precaution, it is better to save personal data (photos, yearbooks, etc.) to an SD card or One Drive to avoid loss.
