Just yesterday, Dona Sarkar and the Windows Insider team released Windows 10 Insider Preview Build 15063.2 for Windows 10 Mobile Insiders in the Fast Ring. Late today, the Windows Insider team has followed up to grace Slow Ring Insiders with the glory of that very same build.

Dona Sarkar did not provide other details, so this build might as well involve the same Fast Ring “fix” which enabled the ability to update to build 15063 from the Windows 10 Anniversary Update (Build 14393) on Windows phones. Even with that so, this latest release replaces build 15051, which is the last build that Slow Ring Insiders had received.
As the April 11th PC launch of the Creators Update nears, we still wish you Slow Ring Windows Insiders well with your downloading, and also invite you to drop us a comment below to let us know how this build is working on your Windows Phone device.
