Microsoft has pushed a new Windows 10 Mobile Creators Update Build 15063.138 to Mobile insiders in Fast and Slow Rings. Windows 10 Mobile Build 15063.138 is in fact the same build that has gone out as cumulative update for non-insider on PC.

You may know that Microsoft has announced official roll-out of Windows 10 Creators update starting today. Windows 10 Mobile Creators Update roll-out however will begin on April 25 and that too to a very limited set of Windows 10 Mobile Phones.

Now coming to the Build 15063.138, even on Mobile it is mentioned as “April 2017 update for Windows 10 version 10.0.10563.138 for arm-based phone devices“. So, it is clear that since Windows 10 Mobile Creators Update roll-out is bit delayed as compared to its PC counter-part, the April update has come to Mobile devices in Fast Ring.

Windows 10 MobileĀ Build 15063.138 doesn’t bring any new feature. It packs couple of fixes that will help in getting better experience with Creators Update. It fixes issues with time-zone information. It also brings security updates for many components.
