Microsoft has released the Windows 10 Insider Preview Build 18305 in Fast Ring. This is the 19H1 development branch, which will be released in spring 2019.
The announcement and a description of the new features can be found in the Windows Blog. In this build, the consolidation of the login options will be further advanced. Users can now set up a security key directly in the settings.
A simplified standard startup layout has been introduced for new devices, new user accounts and clean installations. The new layout has been simplified to a single-column design with reduced top-level tiles. Business and training customers will also see a simplified layout tailored to these scenarios.
Also included in this insider build is the announced Windows Sandbox. I had reported about this new feature in the blog post Windows 10 gets Sandbox for applications. Hints to known issues and further details can be found here.
