Windows Longhorn build 3718 is the last Milestone 3 build of Windows Longhorn, which was shared online on 30 April 2004.[1] It is very similar to build 3713 in features and functionality, albeit with a more stable Windows Explorer.

Changes[edit | edit source]

  • Media Center is now referred as "Media Center" in Add or Remove Programs instead of "Freestyle".

Bugs and quirks[edit | edit source]

General[edit | edit source]

  • Sometimes when the user logs in, the desktop wallpaper may be reset to none.
  • DiskPart does not work and will tell the user that This version of diskpart is not supported on this platform.

Media Center[edit | edit source]

  • Once installed, it is impossible to uninstall Media Center. The only way to uninstall this is to reinstall Windows.

Installation[edit | edit source]

  • When upgrading to this build, the boot menu entry is named Microsoft Windows XP 64-Bit Edition Version 2003 Setup despite being an x86 build.

Control Panel[edit | edit source]

  • Classic View is missing in the Control Panel and many applets are missing. Some of the Control Panel applets can be run by running their executable from Run or Command Prompt. However, if the user upgrades from a previous build and its Control Panel was on Classic View prior to the installation, then the Control Panel can be viewed in Classic View, but the user then cannot switch back to Default View. Alternatively, the Classic View can be enabled by opening Folder Options Control Panel Applet and choosing "Use Windows classic folders".
  • If the WebView key is deleted from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer, the tasks pane will revert to a Windows XP-esque task pane allowing the user to switch between classic and default views.
  • Display Properties mentions the Luna theme as the Plex theme.

MyTVApp[edit | edit source]

MyTVApp now crashes when it is opened, although the Avalon Trust Manager still opens without problems.

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.

Tablet PC[edit | edit source]

The Tablet PC package is broken in this build, resulting in the Tablet PC component unable to install.
