Microsoft is rolling out a new Windows 10 build for mobile. Build 10586 has been released to Windows Insiders in the fast ring, and promises to fix a number of bugs from the previous build.

In the previous build, Build 10581, there was a bug that partially corrupted a user’s file system after a factory reset. As a result, Build 10586 will cause a user’s phone to reboot after the upgrade is completed. Microsoft is providing a hardware key combination users can use to reset their phone, but recommends they backup their phone before upgrading to the latest build. In addition, users can recover their phone using Microsoft’s Windows Device Recovery Tool.

Other known issues in this build include the inability to deploy Silverlight apps through Visual Studio, and the inability to open Insider Hub. Microsoft has provided a workaround in the meantime.

The release also features the ability to set default locations, the ability to move apps to an SD card without causing the apps to crash, improvements to messaging and Skype apps, ability to use the physical camera button, and the capability to download apps and games from the Windows Store.
