Windows Longhorn build 3718

Windows Longhorn build 3718 is the last Milestone 3 build of Windows Longhorn. This build was shared on 30 April 2004. It is very similar to build 3713 in features and functionality, but the Tablet PC features cannot be installed despite the files being present on this build's component media. Alongside, Media Center is now referred as "Media Center" in Add or Remove Programs instead of "Freestyle". Unlike most later builds and even a few earlier builds, it is very stable and is less likely to have Explorer crash.

General

 * Sometimes when the user logs in, the desktop wallpaper may be reset to none.

Media Center

 * Once installed, it is impossible to uninstall Media Center.

Control Panel

 * 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.


 * If the  key is deleted from , the tasks pane will revert back to a Windows XP-esque task pane allowing the user to switch between classic and default views.

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

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.

Tablet PC
You can't install the Tablet PC components, because this build's Tablet PC package is broken.
