Windows 8 build 7850 is a Milestone 1 build of Windows 8. This build was originally leaked as an x86 Enterprise SKU version on 2011-04-12, then on 2015-01-17, an x64 version was leaked of this build along with more SKU's for both the x86 and x64 architectures.[1]

Being early in development, many areas still say Windows 7 and the kernel is still 6.1 (much like builds 7700 and 7746). The default background image of this build is a bluish gradient with a green tint at the lower right and a message at the top telling not to leak this build ("shhh... let's not leak our hard work").

Redpill

The 2020.3.02 build of Redlock unlocks various features in this build. It's the earliest leaked 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.


Other features include:

  • Explorer Ribbon UI (Icons are all circles)
  • User Tile (located at the right of the taskbar)
  • Centered title bar text
  • Built-in PDF Reader (basic)
  • Modern Task Manager (partially broken)
  • Webcam Application (full screen)
  • Auto colorization of themes
  • ApplicationExplorer 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 (basic)
  • Early beta of IE9
  • Built-in, working USB XHCI drivers
  • System reset (sysreset.exe), which has a version build number of 7782
  • Portable Workspace Creator (pwcreator.exe)

Findings, fixes, enhancements

PDF Reader

There is a very early version of the Immersive Reader included, accessible by running C:\Windows\System32\glcnd.exe with any PDF file as an argument (or without any argument to open a blank page).

Modern Windows Task Manager

A preliminary version of the Modern Windows Task Manager is included as well. It is accessible by running C:\Windows\System32\TaskUI.exe.

Ribbon UI

A Ribbon version of Windows Explorer is included as well. However, most of the icons for it are placeholder circle icons.

Webcam Capture Application

An early version of the webcam capture application is included as well, accessible by running C:\Windows\System32\Webcam.exe.

Auto Colorization

Create a copy of a theme from C:\Windows\Resources\Themes, add AutoColorization=1 to the end of the [VisualStyles] section and apply.

Bugs and quirks

  • Windows Classic and the High Contrast themes are broken.
  • Changing the date appears to freeze up the Explorer shell.
  • Using Desktop Gadgets significantly slows the OS down.
  • Upgrade in this build is broken.

Aero

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.

Upgrading to later builds

Newer builds may oddly identify this build as Windows XP when trying to upgrade.
