Windows Longhorn build 3706

Windows Longhorn build 3706 is a Milestone 3 build of Windows Longhorn, which was shared online on 23 May 2006.

New features and changes
- Clock - Slide Show - Quick Launch - Search Bar
 * The default wallpaper has been changed to an aurora image with the Longhorn logo.
 * The Plex theme has been slightly updated to be darker in color.
 * There is now a Download Manager in the Control Panel. However, it doesn't work and opening it only results in the Explorer window hanging.
 * The Desktop Composition Engine has been updated and now has animations for windows that are closed or minimized. It can also be enabled in the Display Properties. A video card driver with Direct3D support is needed.
 * The Explorer details are enhanced in that the icons are now enlarged and animated by slowly rotating back and forth.
 * This build updates the copyright date in  from 1981-2002 to 1985-2003, despite being compiled in late 2002. Thus, Command Prompt only updates 1981 to 1985, leaving 2002 untouched.
 * The Start Page Launcher has been updated and is now more complete.
 * The Sidebar can still be enabled, but doing so will always attach the taskbar along with it.
 * Alongside that, the Sidebar also includes the following widgets by default:
 * The Out of Box Experience no longer includes the question mark indicating if you require help at the beginning of OOBE. However, the next page includes it - just without the animation.
 * The Avalon display properties no longer appears whenever you open up display properties.
 * In "Search", Preview Pane is enabled by default.

WinFS
WinFS folders have been implemented in this build.

Properties of WinFS folders let the user add and delete folders to be scanned in order to show pictures, musics and documents in them (similar to Libraries in Windows 7)

MyTVApp
This build includes a new application called MyTVapp, which opens in an Avalon container in Internet Explorer. It was intended for recording and watching TV from the operating system. It can be run by running  in. It is largely incomplete however, as there are placeholder images in "My TV & movies", "Recorded Shows", and "What's On", while "Guide" leads to a page error and "Search" has no effect when clicked. Interestingly, when attempting to open the MyTVApp, an Avalon Trust Manager opens, warning the user that the application came from an Unknown Publisher and it might be harmful to run.

New file copy conflict resolve dialog
This build, just like the last one has a new file copy conflict resolve dialog, it can be enabled by setting the DWORD value  to 1 in.

Briefcase introduction
This build contains a briefcase introduction dialog, you can open it by running the command

"People" sidebar tile
This build features a normally hidden People sidebar tile. It can be enabled by changing the following values in the registry: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\PeopleTile] "Assembly"="Microsoft.Windows.PPLRTC1" "Module"="Microsoft.Windows.Collaboration.Controls.PeopleTile"

Avalon-based Display Properties
In this build the Avalon-based Display Properties dialog is disabled, but not removed like you may think. To reenable it, set  to 0 in

Removed features

 * Program Manager has been removed in this build. The file for it still exists, but it redirects to Windows Explorer instead.

General

 * The Avalon Trust Manager has duplicated text, overriding the "High Risk" text.

Sidebar crash
Like later componentized builds of Longhorn, attempting to edit or add certain features on the Windows Sidebar like Slide Show can cause  to enter a crash loop. The only way to fix this loop is to remove the conflicting tile from the Sidebar via the Registry.

Desktop Composition Engine
Desktop Composition Engine requires either compatible hardware or VMware Workstation 6.5.x to work (just 6.5x compatibility won't work), otherwise it will result in a black screen that can only be exited by a hard reset.

File differences
The following files have been introduced or removed compared to build 3683 Professional:
