Microsoft releases a cumulative update preview build 14393.82 for Insiders
This update is only for Insiders on the Release Preview Ring
Yesterday, Microsoft began seeding the official Anniversary Update to supported smartphones with build 14393.67. Now a cumulative update for the Redstone 1 branch has been rolled out to members of the Insider program for testing.
Windows 10 Build 14393.82 is live for PCs and phones, but only for Insiders on the Release Preview Ring, and the build comes without a changelog.
Microsoft is expected to release soon the first mobile build from the Redstone 2 branch to Insider Fast & Slow rings, so those of you who want to remain on the stable branch should switch to Release Preview.
Insider Release Preview will be used for preview updates of the Anniversary Update branch – 14393, while Fast and Slow rings will allow you to test builds 149xx and newer. Keep in mind that the first builds from Redstone 2 will likely include many bugs, so you should avoid Fast & Slow rings for now.
