Windows 8.1 build 9364

Windows 8.1 build 9364 is the first and final development build of Windows 8.1 that was shared online on March 24, 2013.

Setup
Setup is visually the same as the previous build, except that there is no "Microsoft Confidential" watermark (it returns in build 9370). The OOBE also has a different color picker for the Start screen, and a different message when an invalid computer name is entered. Finally, the post-OOBE tutorial now has the text "Try this after your PC is ready".

New features and changes

 * The kernel version has been changed to 6.3.
 * New Metro apps (Alarm, Calculator, Movie Moments, Sound Recorder).
 * Improved Snap feature allowing one to snap Metro apps at lower resolutions than in Windows 8 (with the minimum resolution being reduced to 1024x768).
 * This is the earliest available build to contain the "slide to shutdown" feature, and the application for this can be found in, called "SlideToShutdown".
 * User folders (Documents, Music, Pictures, and Videos) have been added to Computer in File Explorer.
 * Windows 7 File Recovery (Backup and Restore) has been removed from Control Panel.

Start screen

 * The "Personalize" charm was updated to include background options, which still feature the same set from Windows 8.
 * A new "Customize" option has been added to the right-click menu.
 * Apps can now be sorted in the All Apps view.
 * Small tiles have been introduced.

PC settings
This build includes a new version of the PC settings app, with an option to switch back to the previous version from Windows 8. Being an early version, there are various imperfections such as the search bar appearing over title text.

Blank screen on boot
This build often boots up to a blank screen after logging in, instead of loading the start screen directly. Left-clicking at the screen or pressing the Windows key can load the start screen and allow the user to continue.

Metro

 * The "Start" text on the preview that appears when hovering on the bottom left corner of the screen is pixelated.
 * The settings charm has different colors on the tiles.

PC settings

 * The search box does not work in this build.
 * If a user switches to the Windows 8 Settings app, they will not be able to revert back to the new version.
