Microsoft also announced a new ring for insiders. Called the Windows Release Preview ring, this group will consist of those who want to stay with the Current Branch of the software (10586) and still receive early access to updates, apps and other changes.
The new Windows 10 Mobile build 10586.107 fixes an issue that left some tiles missing on the start screen after taking the device out of the box. In addition, Narrator now supports the use of multiple languages, and the new build adds improvements to the device reset experience when BitLocker\Device Encryption is enabled by enterprise policy, or by the user.
To download Windows 10 Mobile 10586.107, go to Settings > Update & Security on your compatible Windows Phone handset. It seemed pretty obvious, but as one of our loyal readers has pointed out, we should remind you that you need to have the Windows 10 Mobile Insider Preview app installed and sign up for the Windows Insider program.
