Today is a very busy day on the Redmond campus: the Creators Update has now started to roll out to all Windows 10 users, and we're also getting other Patch Tuesday updates for Windows 10 version 1607 (aka the Anniversary Update) and Windows 10 version 1703 (which is the Creators Update). In addition, Windows 10 Mobile is also getting a cumulative update today with the mobile build 14393.1066, which is now rolling out to users on the Release Preview and Production rings.
We're not sure what's new with this build, as the detailed changelog that Microsoft published for the builds 14393.1066 and 14393.1083 (we're not seeing this last one on any of our devices, to be clear) mostly mentions PC-related stuff such as Internet Explorer, printers and more. That's pretty much the inconvenient with these combined changelogs, unfortunately.
Anyway, you can download this cumulative update by checking Windows Update on your phone settings, and let us know in the comments if you notice any improvements. If you're a Windows Insider on the Fast Ring, we remind you that you can download the Windows 10 Mobile Insider build 15063.138, which was curiously not announced by Microsoft today.
