Similar to the Windows 10 upgrade process for computers, Microsoft has released an upgrade tool to the Windows Store for Windows mobile devices called Windows 10 Upgrade Advisor app, in order to let them know whether or not the Windows 10 Mobile upgrade is available for their smartphones, as well as help them prepare their devices to receive the company's latest mobile OS.
Last but not least, Microsoft has also released a list of eligible Windows Phone 8.1 phone to upgrade to the latest Windows 10 Mobile, which includes Lumia 1520, 930, 640, 640XL, 730, 735, 830, 532, 535, 540, 635 1GB, 636 1GB, 638 1GB, 430, 435, BLU Win HD w510u, BLU Win HD LTE x150q, and MCJ Madosma Q501.
According to Microsoft "As Windows 10 delivers significant new innovations, many older devices are not able to successfully upgrade without an impact on the customer experience. Our goal is to only offer the Windows 10 upgrade to devices that we are confident can continue to deliver a good customer experience".
Windows 10 Mobile is now rolling out to supported Windows Phone 8.1 devices. Although, some users may not get the update immediately, due to device manufacturer, device model, country or region, mobile operator or service provider limitations.
