Based on your feedback, we’re introducing a simplified default Start layout for new devices, new user accounts, and clean installs. The new layout has been simplified into a sleek one column design with reduced top-level tiles. For the IT admins out there, don’t worry, commercial and education customers will also see a simplified layout tailored to these scenarios.
Coupled with earlier changes providing the ability to uninstall additional inbox apps, and a new way to easily to unpin a folder or group of tiles, the simplified Start layout is part of an ongoing effort designed to enhance your Start experience in the upcoming release of Windows.
More details about the new features in this build can be read at the Windows Blog. Besides the Windows Sandbox, which we covered last week, there's some interesting new stuff like the ability to sign in to Windows with password-less Microsoft accounts via an SMS code.
