Windows 10 build 18917

Microsoft recently released a new Windows 10 build with some hidden components. These components indicate that Microsoft plans to separate Windows Shell UI from the base OS. 

Microsoft has not included any major changes in build 18917. We can see the changelog lists more or less the same features included in the first Windows 10 20H1 update.

As the development process is currently in progress, we expect to see more changes in the next build releases.

Albacore shared the details about the new component “Shell Update Agent” on social media.

Albacore went on to add that one of the features that are based on a Shell package is Action Center in Windows 10.

Action Center seems to be among the first few things that even current builds try to source from a Shell package if available. In case something feels off about AC in future builds, this might be why.

Microsoft introduced a new technique to sync settings in the recent build. Windows 10 can now sync both legacy and advanced features.

Albacore quoted the example of File Explorer configuration. As you can see, Microsoft is silently working on a major new feature.

Another interesting thing related to the shell: It appears that Microsoft is silently working on replacing the current Settings Sync implementation with a new one. The new one should support syncing more advanced and previously “legacy” options such as File Explorer configuration. 

If these features pass the testing phase, the changes will be rolled out with Windows 10 20H1 which should land in the first half of next year.

You can download the Windows 10 SDK Preview build to check out the new features.
