 * Numerous new features and commands were added to Cortana. Highlights include the ability to shutdown the PC by asking Cortana, as well as the ability to restart, lock, and put the PC into standby with your voice.

 * Added a UI for Enterprise Cloud Printers, which is located in Settings -> Devices -> Printers and scanners. This feature enables corporate users to discover corporate printers when on Azure Active Directory joined devices. This feature requires backend services to function, which were not available at the time of this build's release.
 * Added support for 19 additional games with the Windows Game Bar, as detailed in the release announcement.
 * Various improvements to Windows Ink Workspace. Highlights include the ability to resume previous sketches in Screen Sketch, an updated flyout for the Windows Ink pen, pencil and highlighter tools. It shows a preview of what the tool looks like with the selected color and width. The flyouts were updated as well to remove duplicate color entries when in High Contrast, as well as adding support for using the Esc key to close the flyout, as well as automatically dismissing the flyout once you choose a color or width. The ruler was updated to rotate in sub-degree increments when you touch it, which makes it easier to line it up with two points on the screen. The cursor now no longer appears when you're inking.
 * Updated the rendering technology for UWP app content.
 * Numerous improvements to Narrator. Highlights include it giving you additional information about fonts, colors, line spacing, margins etc. The Context Awareness level is now set to 2. This results in it reading additional areas on the Start menu and Office's Ribbon UI, as well as other areas. The key to get advanced information about the item in focus has been changed from Caps Lock+F to Caps Lock+0.
 * Added File Explorer's keyboard shortcuts into Registry Editor.
 * Changed the priority of the USB Audio 2.0 driver to be prefered over third-party drivers.
 * Improved the update experience. If Windows Update cannot find a suitable time to restart the PC to apply the latest updates, you will be prompted to either restart now, schedule a different time for the update, or “Remind me later”.
 * Improved high-DPI support for desktop apps.
 * This is the first official build to include the View 3D Preview app.
 * Various improvements for the Chinese and Japanese IMEs. Highlights include improvements to the Microsoft Pinyin IME candidate pane. It is now easier to find a suitable candidate word. A small icon was added to indicate when a particular cloud candidate is trending. A new context menu for the Microsoft Pinyin and Wubi IMEs was added. It contains options to easily access the selected IME's settings page or showing the language bar.
 * Microsoft Pinyin IME now supports importing and exporting self-learned phrases. This means if you reinstall the PC or have multiple PCs to maintain, the same user lexicon can be kept.
 * The Wubi IME was updated to support user-defined phrases.
 * The Simplified Chinese writing panel now supports line mode, just like the Japanese IME. Two editing gestures were also added, a strikethrough for deleting text and a circle for grouping.
 * Improvements to the Japanese IME. Highlights include the ability to remove text prediction candidates, as well as improving the conversion accuracy. It also included some bugfixes as well.
 * Windows Defender has been heavily revamped, from a Win32 desktop app to a UWP app.

Bugs

 * Using keyboard monitor hotkeys to adjust the brightness won't work as expected. You can change the brightness manually via the Action Center or by navigating to Settings -> System -> Display.

 * DirectAccess does not work on some configurations.
 * When using Microsoft Edge with Narrator, you may hear "no item in view" or silence when navigating through tabs or using other navigation commands.
 * Hey Cortana, play (song) on (app name) doesn’t work immediately after installing the app. Wait five minutes for the indexer to activate and try again.
 * The new Windows Defender is in an early state in this build, so most of the features are either missing or incomplete.
