About dialog

Windows 8 build 7785 is a build of Windows 8, which was shared on 18 August 2024 alongside build 7793. It is the last known build to have 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 (much like builds that predate 7875).

Redpill

This build is one of the earliest to contain the Redpill feature locking mechanism, which hides most features found in builds of Windows 8 (and its server counterpart). Most Redpill features that are present in this build do not possess any real functionality or do not properly function.

New features and changes

Desktop Window Manager

Desktop Window Manager now supports automatically changing the window color based on the desktop background. It can be enabled by appending AutoColorization=1 to any theme file's [VisualStyles] section.

Miscellaneous

• The default Aero theme background image has been changed to a blue gradient with a green tint at the lower right, with a message at the top advising Microsoft employees not to leak the contents of the build. This is similarly reflected with the addition of a watermark on the desktop and on the winver application.

Ribbon

This build includes the Explorer ribbon as well, which depends on a registry key and therefore will not be dropped by Redlock. To enable the ribbon, merge the following entry into the registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"RibbonizeMePlease"=dword:00000001

Taskbar

The user tile on the bottom right was added. The hover tooltip shows the currently logged in user's username, however clicking it doesn't do anything. It can be hidden via the system icon settings or a group policy.

Bugs and quirks

Shell

• On DPIs other than 100%, the user tile on the right side of the taskbar is rendered in it's original size, unlike the placeholder.
• Due to a very early implementation, users may encounter some bugs when the ribbonized explorer is enabled:
  • The Windows Explorer ribbon shows all possible options at all times.
  • The ribbon on Windows Explorer is entirely non-functional.

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.
• Only the top portion of the window frame is blurred when using the Windows Aero theme, leaving the side borders transparent.

Installation

• The background seen in the Windows Preinstallation Environment is absent in this build. This quirk persisted until build 7875.

Keyboard layouts

• The Chinese Traditional keyboard layout is enabled by default alongside the English (US) keyboard layout and the user's keyboard layout chosen in Setup (if different from English (US)).
