Windows Server 2008 build 4066

Longhorn Server build 4066 (identifies itself as Windows .Net Standard Server 2003, with a build tag of 4066.main.040226-1010) is a pre-reset Windows Server 2008 build. It was originally described by Grabberslasher in his UX.Unleaked blog entry on 2008-05-01 and leaked on December 20 of the same year.

This build is the second build to leak based on the pre-reset code, the other being build 4028. This build, surprisingly, uses the i386 (Windows XP-esque) installation. This build is often mistakenly identified as a Windows Vista 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.idx02.040425-1535
 * 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.

Bugs

 * The setup cannot format the drive, as it results in an "Unknown Hard Error" BSOD.

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