Windows 10 Mobile Build 15254.603 is the update for Microsoft’s mobile OS.

On January 14 2020, Windows 10 Mobile reached End of Life (EOL), and the last cumulative update is available for everyone. Microsoft is currently rolling out Windows 10 Mobile Build 15254.603 to phones like the Lumia 950 or HP Elite x3, and Microsoft has shipped the final update without a proper changelog.

Windows 10 Mobile Build 15254.603, which is the last update for the OS, comes with security fixes and general improvements. The official changelog points to desktop release notes, which implies that Microsoft may have fixed security bugs affecting Windows Kernel, Windows Input and Composition, and other components.

Four years after Microsoft released the last Windows Phone flagship, Microsoft has confirmed that Windows 10 Mobile has reached the end of all support. You can still use your Windows Phone, but various apps, such as WhatsApp, may not work.

After today, you can still back up your device, settings and data of specific apps, but these features will be scrapped on March 10th, 2020. Some backup features, including photo uploads, may continue to work for up to 12 months.

Although Microsoft is not treating the Office Mobile apps for Windows 10 as a priority, they’re planning to support the apps on Windows 10 Mobile for another year. Support for Office apps will end in January 2021, and the apps will receive essential security updates for at least one year.

Microsoft: Switch to Android or iOS

Microsoft has been recommending Windows 10 Mobile users to switch to a supported Android or iOS device.

Microsoft is actively developing and updating apps for other mobile platforms, and the company offers a wide range of apps, including a dedicated launcher for Android.

Microsoft has also created an app called ‘Your Phone‘ that preserves the most essential features of an Android phone: messages, notifications, and calls. You don’t need to take out your phone from your pocket to access its contents while working on Windows 10.

Currently, the Your Phone app allows you to access photos stored in your Android phone from your PC, and it also lets you access your text messages, initiate calls, and mirror your Android screen. Eventually, Your Phone platform will also support document sharing with Windows 10 computers.
