Windows 10 build 10549

Release date: 10/14/2015

Known issues in build

Due to a bug in the upgrade flow, this build is only available as a single update from Windows Phone 8.1. Current Insiders that would like to try out Build 10549 should:

  • Go back to Windows 8.1 first using the Windows Device Recovery Tool.
  • Once you’re on Windows Phone 8.1, install the Windows Insider app, choose the Fast ring, and reboot your phone.
  • After that – this build should download and install on your phone

Users on 10536 will not be automatically upgraded. We are working to ensure that these users can move forward to a future Insider build.
