Windows 8 build 8064

Windows 8 build 8064 is a Milestone 3 build of Windows 8, which was uploaded to BetaArchive on 23 January 2021. This build was released to Microsoft partners through the Ecosystem Engineering Access Program (EEAP) and as is common for such builds coming from the  branch, it had the entire Metro user interface stripped out at compile time and therefore cannot be redpilled in its vanilla state.

It is the last known build of Windows 8 that has the wordoku puzzle background with the leak warning; it would be replaced with the Windows 7 logon wallpaper in build 8102, as well as the last to include classic built-in games (such as Solitaire, Minesweeper) from Windows 7.

Changes

 * 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.
 * The BSOD is now reminiscent of the RTM build.

Timebomb
This build contains a broken timebomb and as a result can be installed on the current date.

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

Windows Setup
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

 * 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, the OOBE background is improperly displayed.
