Windows "Longhorn" build 3683 (with a build tag of 3683.Lab06_N.020923-1821) is a build of the Microsoft Windows "Longhorn" operating system. Compiled on September 23, 2002, build 3683 is one of the first builds leaked to the public on November 19, 2002,^[1]^[2]^[3]^[4]^[5]^[6]^[7] after some screenshots have been published since October 20, 2002.^[8]^[9] Due to the operating system being so early in the development process, only a small number of changes were observed from Windows XP. It is the first build to include the Desktop Composition Engine,which provides window transparency and visual effects, but it's very buggy.

Features in build 3683 include the Plex visual style, Internet Explorer 6.05, the Windows Sidebar, and a display settings applet based on the Windows Presentation Foundation (then codenamed Avalon).

Build 3683 is incompatible with a number of applications that require Windows XP or earlier. Many of these compatibility issues can be solved by running applications in Windows Compatibility Mode or by editing the CSDVersion key located in the Windows Registry.

Although this build is stable when compared to later builds of "Longhorn", Windows Explorer is known to crash frequently and will occasionally fail to terminate while ending the computer session.

Main changes

This build showed for the first time:

the new Plex theme^[10]

a new sidebar, where it was possible to integrate XML-based components called "tiles", including a clock, a photo slideshow, a multiple desktop manager, a list of most frequently used programs, the Quick Launch toolbar, an Internet search bar, and a user tile, to quickly switch between users. The sidebar could also be combined with the taskbar^[10]
WinFS, called "Windows Future Storage" in this build. The WinFS services run by default, which slowed down the system, but no WinFS features are integrated in Windows Explorer^[10]
a new "Display Properties" control panel, written with "Avalon" APIs, most of which was not functional except for Display Connection Settings, which provides information about the display adapter and monitor.^[10]
new version 6.05 of Internet Explorer, with the new "Media" bar^[11]
a beta version of DirectX 9^[11]

Several new features appeared in Windows Explorer:

a new big horizontal panel under Windows Explorer toolbars, called "breadcrumb bar", which can be disabled from "Folder Options", with custom appearance for special folders "My Documents", "My Pictures", "My Music", with animated effects on thumbnails in the case of multiple selections^[10]^[12]
the new "My Contacts" special folder (not yet functional)^[10]
an enhanced address bar (see Gallery)
previews of the folder contents inside their icons in the "Tiles" view mode (see Gallery)
filtering the folder contents in the "Details" view mode in Windows Explorer;^[13]

a new slider to change the icon size^[13]
the possibility to group the folder contents with specific criteria (e.g., Documents Grouped by Type)^[11]
the possibility to select files and folders through checkboxes (see Gallery)
a new interface for "Save As" dialog windows^[11]
