Windows 8 build 7779

Windows 8 build 7779 is a build of Windows 8, which was shared by a community member on 27 June 2022 alongside build 7777. It is the last known build to feature the Getting Started applet and the option to enable the Windows Classic theme via the Control Panel.

Due to its earliness, many areas still say "Windows 7" and the kernel version is still 6.1.

Aero
This build reintroduces centered title bar text, which was last featured in Windows Longhorn build 4005. Title bar text and caption buttons were also made larger by default.

Unlike build 7814, the title bar text alignment is still a bit left-aligned because it is in the center between the icon and the Minimize button instead of the center of the whole title bar.

ISO mounting
This build is the first build to natively support mounting of ISO disc images; a "Mount" option has been added on the right-click menu of ISO image files for this purpose.

Multimonitor taskbar
This build adds the ability for the taskbar to be displayed on multiple monitors. It works substantially better than build 7788's implementation, such as working on more than two monitors.

Windows Explorer
A redesigned status bar has been implemented into the Windows Explorer, which includes options for toggling different panes and views.

Redpill
Redpill is now functional unlike the the previous build's, where the  binaries were simply binary stubs. The start screen displays "(Launcher)" due to the DirectUI XML styling of the start screen stating  instead of , which makes DirectUI interpret the styling as a request to place the literal text   in the centre of the screen (as there is no styling to move it anywhere else) instead of a request to bind and show the content of the control. However, currently fixing this results in a white screen. The Metro Horizon has also been implemented.

Ribbon
This is the first build to include the Explorer Ribbon. However, it uses a unique registry key not in any other build and therefore will not be dropped by Redlock.

To enable the Ribbon, copy this to a registry file and open it, or add the key manually:

Windows Store
This build's Windows Store is identical to build 7777, and can be patched in the same way as that build.

Hyper-V
If Hyper-V launch fails, messages asking the user to enable virtual machine extensions will be printed directly onto the boot screen instead of being spewed as an Event Tracing for Windows (ETW) log.

Watermark
The "Windows 7" section of the watermark has had its size changed due to the increasing of the title bar text size.

DWM and Aero

 * The Aero functionalities do not work on modern versions of VMware Workstation and above due to changes that are incompatible with the graphics stack. Using either VirtualBox or VMware with the 9.x hardware compatibility or older and using 9.x drivers or older is recommended.
 * This build appears to have a slightly broken Windows Aero theme, with only the top portion of the window frame using the blur effect, leaving the side borders transparent.
 * When upgrading from build 7777, DWM may encounter a  error when logging in. If faced with a black screen, press Ctrl to show the Windows security screen, in which the user can press OK then cancel to reach the desktop.

Multi-monitor Taskbar

 * Changing the screen resolution of the second monitor will cause the taskbar appearing as a large white line and the wallpaper will not be correctly resized. Restarting  will fix these issues.
 * After an app is closed, the program's icon will still appear on the second monitor's taskbar unless a new program is dragged to the second monitor.

Help and Support Center
Navigation throughout the Help and Support Center might fail as the program is "undergoing major reconstruction".
