Yesterday, we reported that Windows 10 Mobile build 10586.164 was in internal testing and that the next stop would be the Insider Preview. Today, that"s a reality. In fact, it"s not just available to the Insider Program. It"s in the Production ring right now for anyone running Windows 10 Mobile.
The firm has also released the build to both the Slow and Release Preview rings. If you have a device running Windows 10 Mobile Insider Preview that"s not supported by the Redstone builds (14xxx), as with the last build, you need to switch your device over to either the Slow or Release Preview ring to get it.
The build is a cumulative update, so it focuses on fixes instead of features.
Jason from Microsoft says:
Q: Who is receiving this build?
A: This release is being sent to Retail open market devices as well as our Insiders in the WIP Slow and Release Preview rings.
Q: I"m in the WIP Fast ring. How do I obtain this .164 release?
A: Change rings in the Windows Insider app to either WIP Slow or Release Preview, take the update, and then change back to the WIP Fast ring.
Q: Why is it necessary for WIP Fast users to switch rings?
A: It"s a publishing limitation. Changing rings will not be a permanent process, but it is required for this particular release.
Q: Why didn"t Insiders get to test this release before releasing it to Retail users?
A: Insiders did get to test it! The previously released 10586.122 build is nearly identical to this new .164 build. There are no major feature changes between the two builds. Changes were focused on a few key bug fixes and other required updates to ensure this build was ready to release to Retail users.
