Microsoft pushes Windows 10 Mobile update to non-Insider testers

On Friday, Microsoft pushed Windows 10 Mobile Insider Preview build 10586.29 to Fast Ring testers. Yesterday, Slow Ring testers also received the update. However, today, non-Insider project participants also began to receive push notifications for build 10586.29. It is reported that Lumia 950 / 950 XL owners, as well as Lumia 550 users in the UK, have received this Windows 10 Mobile update.

According to some reports, Windows 10 Mobile build 10586.29 has also been rolled out in some other parts of the world. Such a fast move shows that Microsoft is sticking to its promise to deliver on time.

In May, a company spokesperson said the company would have greater control over Windows 10 Mobile updates, rather than handing them off to slow-moving carriers or manufacturers.

Nevertheless, according to a Microsoft support page detailing how Windows 10 Mobile users can check for updates, "upgrade availability may depend on model, region, and network service provider/carrier."

Oddly, the above description specifically refers to Windows 10 Mobile OS, not Windows Phone 8.1. However, on that page, Microsoft also provides a link to the availability of Windows Phone 8.x upgrades.
