== New features and changes ==
=== Shell ===
Most of the changes that were first introduced to a subset of users in build 20161 are now enabled by default on clean installations. These include the theme-aware Start menu, the removal of the Tablet mode quick action, and the migration of the Control Panel's System applet to the Settings app, and the ability to copy the information in said section of said app.
A notification will show up when an NVMe solid-state drive is about to fail. Clicking on the notification or navigating to Settings Manage disks and volumes properties page will provide an insight to users regarding about the current state of the affected drive.
=== Applications ===
Your Phone app settings page has been redesigned.
== Findings ==
=== New out-of-box experience ===
This build contains a new out-of-box experience, with a similar design to Windows 10X's. It can be enabled by toggling Velocity ID 26336822 via ViveTool, and then running SysPrep. While it is mostly complete, some sections still use older design, such as the EULA and connect to a network section.

=== Theme-aware splash screens ===
This build also contains redesigned splash screens for UWP apps, which no longer use an accent-colored background and use instead a black or white one depending on the theme. It can be enabled by toggling Velocity ID 25936164 via ViveTool, and then restarting Windows. After restart, the splash screens should be updated. However, this only supports the following apps, meaning that any other app that is not in the list will still have the accent-colored splash screen after enabling the feature:
* Microsoft Store
* Feedback Hub
* Settings
* Groove Music
* Movies & TV
* Snip & Sketch
* Windows Security
