Windows Server 2008 build 4066

Windows Server 2008 build 4066 (identifies itself as Windows .Net Standard Server 2003) is a pre-reset build of Windows Server 2008. It was originally described by Grabberslasher in his UX.Unleaked blog entry on 2008-05-01 and leaked on 2008-12-20.

This build is the fourth leaked build based on the pre-reset code, the others being builds 4028, 4031 and 4038. This build, surprisingly, uses the i386 (Windows Server 2003-esque) installation. This build is often mistakenly identified as a Windows Longhorn build when in fact it is Windows Server 2008.

Features
Although it was described a "Server" build, it contained features typically seen in Longhorn client builds. These include:


 * Desktop Window Manager
 * Glass - It can be activated by the keyboard shortcut "Ctrl+Shift+F9".
 * Aurora - "3D view" option on View Options
 * Phodeo - "Panorama" option on View Options
 * Sidebar - with most of the tiles seen in build 4074
 * Windows Media Player - a version of WMP that was apparently intended to replace the traditional one bundled with Windows (in this case WMP9, which is disabled by default). This build also included a WMP tile.

MILRender
An early version of MILRender is found in this build. It includes Aero stars effects and extended aero, as seen in 4074.

Bugs and quirks

 * On some computers and virtualization software, setup cannot format the drive, as it results in an "Unknown Hard Error" BSOD.
 * This build cannot be upgraded from a previous build, and can only be clean installed.
