Windows 10 Mobile build 10586.242 for Release Preview Ring now live

If you are on the Insider Release Preview Ring aka the most stable before it hits production – then you will want to check your phone for an OS update.

Build 10586.242 is a bump from the production release of build 10586.218 and continues to improve and fix the Windows 10 Mobile OS.

Microsoft has not yet posted a changelog nor have there been any announcements making this update a bit of a surprise (along with its unusually late timing). We suppose Windows as a Service (WaaS) means just that so updates can come whenever. In fact, this marks the fifth OS update for Mobile (including Production and Fast Ring) over the last ten days, which is rather impressive.

For users not on the Window Insider program build 10586.242 will likely go out to production after some initial testing, feedback, and telemetry. No new features are expected, but the last two build (.168 and .218) have been fantastic experiences for many.

Rod H., who sent us a tip noted he is updating his Verizon Lumia Icon to the latest release build as well, which is always good news for those looking to keep that 8.1 device ticking in 2016.

Let us know in comments if you find anything new and we'll post a changelog if and when one becomes available.

Thanks, Rod H., Charles S., and others for the tips!
