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 via the Ecosystem Engagement Access Program (EEAP) and as is common for such builds from the  branch, it had the entire Metro UI stripped out at compile time and cannot be redpilled in its vanilla state. It is also one of the first known builds to use the "Windows Developer Preview" branding on the boot screen, and features an updated BSOD reminiscent of the RTM build.

If looked at closely, the caption buttons on the window title bar are now the same size as the ones found in Windows 7, unlike previous builds of Windows 8. It is also the last 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.

Installation

 * It is recommended to use the keyboard in order to navigate through the initial setup interface as the mouse cursor is invisible due to a bug.
 * 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.
 * The System Preparation Tool does not properly function in this build and will run into an error, whether you're preparing for the OOBE or for audit mode.
 * Like previous unredpilled builds of Windows 8, the OOBE background is improperly displayed.
