Windows Longhorn build 4008

Windows Longhorn build 4008 is a Milestone 4 build of Windows Longhorn. This build was leaked on 28 February 2003.

Setup
Setup hasn't really received that much changes in comparison to build 4005.

New features

 * This build updated the Plex theme to be more reminiscent of the Luna theme.
 * This build also had many updates made in the folder windows. For example, the My Documents details background color has changed from blue to tan.
 * The Plex theme has received major overhalls, including different gradients for the title bars and revamped buttons

Parental Controls
This is the first build to include Parental Controls, which can be used to limit the hours that can be used on the computer and monitor the use of internet programs. Only limiting hours that a user can use the computer has been implemented.

The Administrator account can set a limit to any limited user account, including the Guest account. When it is set, the limited user account with the restriction can only use the computer for the specified times the Administrator set. When the time the person can use the computer is past, it automatically performs a "Switch User" operation. Any attempt to log in at a disallowed time will result in a "wrong password" message if the user had a password, regardless of whether the user entered the correct password or not. If that user doesn't have a password, then it will place a password on that account until the user is allowed to log in again.

Hidden Sidebar tiles
A few Sidebar tiles are disabled by default in this build. These are:


 * RMA Test Tile - Just the "Longhorn" clock png stretched in the tile.
 * Longhorn Status - Links to an intranet link at Microsoft.
 * Internet Webcam - Links to a live image of a Redmond, WA freeway, similar to the Traffic ticket from Sideshow, a prototype of Sidebar from Microsoft Research.
 * Media Player - Non-functional. Windows Explorer will crash if you try to open a file.

A registry patch was made available by AlphaAddict that enabled the aforementioned tiles in 2006, but the download link no longer works. On 2020-03-27, it was discovered that it is possible to enable them by merging a registry file with the following content:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\Longhorn Status] "AssemblyName"="ShellInterop" "Friendly Name"="Longhorn Status" "Type"="System.Windows.Desktop.SharePointTile" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\RMA Test Tile] "AssemblyName"="Microsoft.Windows.Client" "Friendly Name"="RMA Test" "Type"="System.Windows.Desktop.RMATestTile" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\Internet WebCam] "AssemblyName"="ShellInterop" "Friendly Name"="Internet WebCam" "Type"="System.Windows.Desktop.StartBarInternetTile" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\{8424cd74-e3d3-4bc7-87ad-15f569922c1a}] "AssemblyName"="ShellInterop" "Friendly Name"="Windows Media Player" "Type"="System.Windows.Desktop.WMPTile"

Windows Explorer must be restarted after applying the registry file.

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartBar\Modules\{62F329E0-B71B-4DDA-8323-628AC066531D}] "AssemblyName"="Microsoft.Windows.PPLRTC1" "Friendly Name"="Messenger Status" "Type"="MS.Internal.Communications.Controls.MeTile"
 * Messenger Status Tile - This tile only works if you are using Windows Messenger. You cannot use MSN Messenger with this tile. Also, this tile does not work with Windows Messenger 4.0, you will need 4.6 or 4.7 for it to function correctly. In order to activate this tile, apply a registry file with the following content:

Bugs and quirks

 * Many drivers aren't installed by default during the hardware portion of setup and have to be installed manually.


 * Unpartitioned drives cannot be selected for installation in the setup. To setup from a hard drive without any partitions, select the disk that Windows will be installed on.
 * If there is an existing partition, the partitioning section of setup will error.
 * The Desktop Composition Engine is heavily broken in this build, so the animations and window transparency cannot be enabled.
 * On older CPUs, the OOBE can error out upon loading. To get past this, press Ctrl-Alt-Delete to load Task Manager and kill the process.
 * Upgrading from Build 4005 results in the theme service producing
