Windows 8 build 7814

Windows 8 build 7814 is a build of Windows 8. This build was shared on the BetaWiki Discord server on 30 September 2021. Prior to this build being shared, a screenshot was included with the original upload of build 7746 on 3 May 2020. It is the earliest available build to include the Redpill feature locking mechanism. It is also the earliest available build of Windows to include a leak warning in the watermark.

Due to its earliness, many areas still say "Windows 7" and the kernel version is still 6.1 (much like the earlier builds 7700 and 7746). The default background image of this build is a blue gradient with a green tint at the lower right and a message at the top advising Microsoft employees not to leak this build.

Redpill
The 2 March 2020 build of Redlock unlocks various features in this build. It is the earliest available build to implement Redpill.

The Start screen in this build is rather primitive, having only one view featuring every installed application with a tile. It also includes a button to bring up an early search pane. A very early and non-functional snap UI is seen when you exit from the Start screen. A primitive Charms bar is also implemented and is accessible by pressing Win + C on your keyboard, but it is non-functional. New folder icons, along with a preview grid, are present in this build when Redpill is enabled. The next build's Metro is almost identical to this build.

Other features include:
 * Explorer Ribbon UI
 * User tile (located next to Show Desktop)
 * Centered title bar text
 * Explorer up button
 * Built-in PDF reader
 * Built-in USB xHCI drivers
 * Built-in UASP drivers
 * Modern Task Manager
 * Full-screen webcam application
 * ISO mounting functionalities
 * Theme auto-colorization
 * Application Explorer shell location (Applications.{4234d49b-0245-4df3-b780-3893943456e1}) - tabs include "Tile state" and "Host environment". This is where the Start screen app list is stored, even up to 8.1.
 * Aero Lite (labeled "Windows Classic")
 * Early version of Internet Explorer 9
 * Certificates and digital signatures that recognize the SHA256 algorithm
 * New Disk Cleanup
 * System Reset
 * Inclusion of Hyper-V in the Professional and Ultimate SKUs
