Microsoft is releasing a brand new build of Windows 10 19H1 to Insiders in the Fast Ring today. Build 18305 is the latest 19H1 build, bringing a couple of new features and a number of fixes for Insiders.
The highlight feature of build 18305 is Windows Sandbox, a new feature in Windows 10 Pro and Enterprise that allows users to test untrusted apps in a lightweight, sandboxed Windows 10 environment. The feature essentially starts up a virtual, lightweight Windows 10 environment where you can test whatever you like for improved security and privacy. The feature is disabled by default, and it needs to be turned on from Optional Features in Windows 10 before you can start using the sandboxed environments.
Build 18305 also introduces a simplified Start Menu layout. Microsoft is cleaning up the Start Menu into a single column layout for improved simplicity, with a reduced number of top-level tiles. This is the default Start Menu layout that appears when you get a new device, for clean installs, or for new accounts. The one column layout should make things feel less cluttered, but all the bloatware that comes with Windows 10 will still likely make the Start Menu look ugly.

Microsoft is also tweaking the Settings app’s design, introducing a new header at the top. The new header gives users quick access to some of the most important things like signing into their Microsoft Account or managing it, system status, and more.
The new build brings a number of other new features, including Tamper Protection in Windows Security, Kaomoji and Symbols on the emoji picker, more compact design for Cloud Clipboard, ability to sign in to Windows with SMS codes for those with password-less Microsoft accounts. The update brings some useful features like the ability to set a default tab on the Task Manager, a wider rollout for Friendly Dates in File Explorer, recommended/automatic troubleshooting, and more.
Windows 10 build 18305 is available to those part of the Fast Ring. You can get the full changelog here.
