On December 8, 2015, Microsoft released Windows 10 and Windows 10 Mobile updates on a global scale testing the Windows as a Service (WaaS) model. Besides the syncing of cumulative OS updates between desktop and phone, the event revealed that carriers seem to be sidelined. Here is why that is and what changed between Windows Phone 8.1 and Windows 10 Mobile.
The reason for the excitement yesterday was the release of Windows 10 Mobile build 10586.29 to the Lumia 550, Lumia 950 and Lumia 950 XL including on AT&T, which came as a surprise.
Interestingly, the update itself is rather ho-hum with no new features, but a few important under the hood fixes. Most users are reporting better standby battery life, improved Bluetooth compatibility and a more enjoyable Edge experience. But let's be clear: there is nothing dramatic, dire, or security-related about this update that would require an emergency release. No, this is a standard cumulative update released on Patch Tuesday just like it was for the Windows 10 desktop.
