Windows XP build 3790.1069

Windows XP Professional x64 Edition build 3790.1069 is the earliest leaked build of Windows XP Professional x64 Edition. This build is based on the Server 2003 version and thus has the Windows Classic theme by default with no background. 32-bit Internet Explorer and Windows Media Player does not function. This build still identifies itself as Windows XP 64-Bit Edition 2003.

Installation
This build needs to be installed on an AMD processor, otherwise this build will encounter a BSOD while booting setup. QEMU, VMware, and VirtualBox are known to install this build, although it is recommended to use an AMD CPU on the host for the latter two to prevent the BSOD.

SysFader
SysFader fading effects can be broken in this build and cause Explorer and other applications to hang when displaying menus. Using the scroll effect for menus will fix this bug.
