Hello Windows Insiders,
Today, we are beginning to test the throttled approach we intend to use to rollout 19H2 to customers with Windows Insiders using the Release Preview ring. This is not the final 19H2 build that we intend to make available via the Release Preview ring once we are closer to launch.
For a small subset of Insiders (around 10%) in the Release Preview ring, we have enabled the “seeker” experience for 19H2. For these Insiders, if they go to Settings > Update & Security > Windows Update, they will see that there is a Windows 10, version 1909 update available. They will be able to choose to download and install this update on their PC. After the update finishes, they will be on 19H2 Build 18363.327.
As John Cable mentioned in July, we will be delivering 19H2 to customers using our servicing technology (just like the monthly update process) for customers running the May 2019 Update (19H1). We have been testing 19H2 with Insiders in the Slow ring using the same baseline build number as the May 2019 Update but with an increased revision number like we normally use to show a build has been serviced with a Cumulative Update. However, to designate 19H2 as a feature update, we are revising the baseline build number by one full build.
Insiders in the Release Preview ring who get 19H2 Build 18363.327 today will not see all the 19H2 features the Slow ring currently has as not all the features have been incorporated into the build yet. Because of the differences between the way the 19H2 updates are packaged between the Slow and Release Preview rings, Insiders in the Slow ring will not be able to switch to the Release Preview ring and get updates yet. Insiders who are thinking of switching rings should stay put for now. We will communicate to Insiders when it is ok to make the switch.
Dona and Brandon
