Windows 8 build 7850 is a Milestone 1 build of Windows 8. It was the first leaked version of Windows 8 on 2011-04-12. Initially, this build only leaked as an Enterprise SKU image. Only much later, in January 2015, additional SKUs leaked.

Being early in development, many areas still says Windows 7 and the kernel is still 6.1 (in a similar manner to XP build 2202 and build 2211, 8.1 build 9299 and 10 build build 9780 and 9785). The default background image of this build is a blueish gradient with the note not to leak this version ("shhh... let's not leak our hard work").

Bugs

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.

Findings, fixes, enhancements

PDF Reader

While there is a very early version of the built-in PDF Reader included, it is disabled by default. It can be enabled using the following registry script:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Applets\Paint\Capabilities]
"CLSID"="{D3E34B21-9D75-101A-8C3D-00AA001A1652}"

and then running C:\Windows\System32\glcnd.exe with any PDF file as an argument (or without any argument to open a blank page). It is not required to disable Aero to run the PDF Reader.

Modern Windows Task Manager

A preliminary version of the Modern Windows Task Manager is included as well. To enable it, run the following registry script:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\TaskUI]
"TaskUIEnabled"=dword:00000001

and then open C:\Windows\System32\TaskUI.exe.

Ribbon UI

A Ribbon version of Windows Explorer is included as well. To enable it, use the following registry script:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CLSID\{4F12FF5D-D319-4A79-8380-9CC80384DC08}]
"AppID"="{9198DA45-C7D5-4EFF-A726-78FC547DFF53}"

Webcam Capture Application

An early version of the webcam capture application is included as well. To enable it, run the following registry script:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize]
"RemoteFontBootCacheFlags"=dword:0000100f

and then run 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.
