Microsoft officially ended support for Windows 10 Mobile on December 10, 2019. Following this, they began the process of deprecating associated services.

  2. Server Support: Even if you manage to sideload the app or find an old installation, the backend servers that facilitate the OS upgrade have largely been dismantled. The app will likely tell you that "no updates are available" or fail to connect to the update service.

Why Did You Need the Upgrade Advisor App?

Before we dive into how to download it for free, let’s revisit why this app was essential:

  1. Hardware Validation – Windows 10 Mobile required at least 8GB of internal storage, 1GB of RAM (though 512MB devices could run a stripped-down version), and a compatible Qualcomm Snapdragon processor.

  2. Firmware Readiness – Some devices needed specific firmware updates (e.g., Lumia Denim) before upgrading. The Upgrade Advisor checked this.

  3. Reserved Storage – The app would create a 3-5GB reserved partition on your phone to download the new OS, preventing upgrade failures due to low space.

  4. Carrier Approval – For some region-locked phones, carriers had to approve the upgrade. The Advisor verified this.

Without this app, many users would see generic “No updates available” messages, even when their hardware was capable.
