Windows Longhorn build 3706 is a Milestone 3 build of Windows Longhorn, which was shared online on 23 May 2006.[1]

New features and changes[edit | edit source]

  • 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 Compositing 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 winver.exe from 1981–2002 to 1985–2003, despite being compiled in late 2002. Thus, Command Prompt only updates 1981 to 1985, leaving 2002 untouched. This persists up to pre-reset build 4067 and post-reset build 5048.
  • 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:
    • Clock
    • Slide Show
    • Quick Launch
    • Search Bar
  • The Out of box experience no longer includes the question mark indicating if the user requires help at the beginning of OOBE. However, the next page includes it - just without the animation.
  • In "Search", Preview Pane is enabled by default.
  • The letters Q and Z have been removed from Dialer.

AutoPlay[edit | edit source]

  • The option to turn off AutoPlay for a selected device has been added.
  • The interface for mixed content has been updated.

WinFS[edit | edit source]

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, music and documents in them (similar to Libraries in Windows 7).

MyTVApp[edit | edit source]

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 mytvapp.container in SYSTEM32. 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[edit | edit source]

This build, just like the last one has a new file copy conflict resolve dialog. It can be enabled by setting the DWORD value NewResolve to 1 in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer.

Briefcase introduction[edit | edit source]

This build contains a briefcase introduction dialog.[2] It can be opened by running the command rundll32 syncui.dll,Briefcase_IntroW.

"People" sidebar tile[edit | edit source]

This build features a normally hidden People sidebar tile.[3] It can be enabled by changing the following values in the registry:

Windows Registry Editor Version 5.00


Avalon-based Display Properties[edit | edit source]

In this build the Avalon-based Display Properties dialog is disabled by default, but not fully removed. To enable it, set ClassicDisplayCPL to 0 in HKEY_CURRENT_USER\Control Panel\Desktop.

Bugs and quirks[edit | edit source]

General[edit | edit source]

  • The Avalon Trust Manager has duplicated text, overriding the "High Risk" text.
  • Windows Media Center will close upon launch.
  • DiskPart does not work and will tell the user that This version of diskpart is not supported on this platform.

Sidebar crash[edit | edit source]

Like later componentized builds of Longhorn, attempting to edit or add certain features on the Windows Sidebar like Slide Show can cause explorer.exe 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 Compositing Engine[edit | edit source]

  • When Desktop Composition Engine is enabled, it renders the graphics on the hardware layer, while the software layer is rendered as black or leftover data, which means that attempting to use software capturing methods (such as Print Screen) will not produce the screen correctly. Most hypervisors only renders the software layer, usually resulting in a black screen upon starting DCE.

Control Panel[edit | edit source]

  • Display Properties mentions the Luna theme as the Plex theme.
  • The new Display Properties Avalon applet has duplicated text in the "Use Classic Display Control Panel" item.
