Windows Longhorn build 4066

Windows "Longhorn" build 4066, with a build tag of 4066.main.040226-1010, which is one of the most unstable version of [[Windows Vista|Windows Longhorn] with many bugs and errors. It was leaked on 2004-02-26.

This build, though, the winver display Windows .net Standard Server instead of Windows Longhorn which is quite not normal, and at bottom-right corner (not the sidebar) you will see it displays: Windows .net Standard Server 2003. This is because Windows Longhorn was based on Windows Server 2003 codebase.

Bugs

 * Broken Preview Pane (Windows Explorer).
 * Sidebar tiles are broken.
 * Broken DWM where it only shows green placeholders instead of Aero glass.
