About dialog

Windows 8 build 8064 is a build of Windows 8, which was released to Microsoft partners through the Ecosystem Engineering Access Program (EEAP) around 15 August 2011 and as is common for such builds coming from the fbl_eeap branch, it had the entire Metro user interface stripped out at compile time and therefore cannot be redpilled in its vanilla state. It was publicly uploaded onto a Google Drive account on 22 January 2021. The x64 version of this build was shared on 28 October 2024.

Prior to its upload, a setup screenshot, and screenshots of the setup.exe's file properties were shared to PCBeta on 16 August 2011.^[1]^[2]

Changes[edit | edit source]

The Welcome message has been removed from the loading screen when booting from the installation media.
This is one of the first known builds to use the "Windows Developer Preview" branding on the boot screen.
Caption buttons on window title bars are now the same size as the ones found in Windows 7, unlike previous builds of Windows 8.
The default user icon has been updated to the one used in the official Developer Preview build, albeit with greenish black background instead of green.
Removed all of the Windows 7 wallpapers and themes except for the regional ones.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

Compatibility[edit | edit source]

To install or run this build in VMware Workstation, the hardware compatibility version must be set to versions 8.x/9.x; otherwise, a partially garbled system crash message will appear upon boot.

Windows Setup[edit | edit source]

It is recommended to use the keyboard in order to navigate through the initial setup interface as a bug prevents the mouse cursor from being normally displayed.

OOBE[edit | edit source]

The System Preparation Tool does not properly function in this build and will run into an error, regardless of whether the system is being prepared for the OOBE or for audit mode.
Like previous unredpilled builds of Windows 8, this build's Windows 7 OOBE background is in monochrome on the left, and on the right, it is entirely black.
