Windows Longhorn build 4082 is a Milestone 7 build of Windows Longhorn. On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was released in the twelfth and final set of his 33 Longhorn/Vista builds on 4 February 2020 along with the main compile of 4042, build 4087 and build 5492.

Bugs and quirks

Installation

As typical of builds in this build range, it tends to take a long time to install and can be unstable.

No mouse driver in WinPE

On some computers and virtualizers, the WinPE doesn't support the mouse, so you must use the keyboard to navigate the WinPE. This seems to be related to using a PS/2 mouse, as USB mice seems to work fine for the setup.

Upgrade

Attempting to upgrade from other builds is not possible as one of two outcomes may occur:

1. A bugcheck with error code 0x7E after the second reboot. This is commonly observed when trying to upgrade from non-componentized builds, such as 4074 (via a registry tweak that reports it as a componentized build).
2. An error during the file copy phase.

WordPad

WordPad does not start, as it will display with Failed to create empty document instead.

Outlook Express

Outlook Express does not start due to registry errors and certain dependencies on WinFS.

Themes

• The Windows Classic theme does not function due to a broken Windows Classic.theme file.

Explorer

• CD and DVD drives behave like local disks.
• Help and Support crashes Explorer.
• Explorer will crash after adding the display tile in sidebar and won't launch again. A workaround is to create a new account via cmd.

Control Panel

• Hardware and Devices folder does not open.
• Sounds Control Panel applet is missing.
• Task Scheduler from Control Panel shows a nameless folder and generic folder icon.
• By default, the Phone and Modem Options Control Panel applet name is empty.
• Computer Management displays script errors due to missing registry entries.
• Device Manager has a bug that drivers can't be updated due to the Hardware Wizard Control Panel applet is missing. You can install drivers by using devcon utility from the Windows XP Driver Development Kit (DDK), or copy the hdwwiz.cpl from another build to the WINDOWS\SYSTEM32 directory in order to get the updating drivers via Device Manager to work.

Creating folders

The option to create folders by right-clicking and selecting New doesn't work as the Folder entry is missing. Apply the following registry key to fix this problem:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.Folder]
@="Folder"

DirectX

Although the Desktop Window Manager is present and can be activated by pressing Ctrl+⇧ Shift+F9 as in Windows Server 2008 build 4066, it will black screen due to a broken DirectX installation. It can fixed via the instructions listed on the Windows Aero page.

Graphics

Enable VGA Mode after installing video drivers or the system will result in a blue screen of death with a error code 0x000000B4.

Windows Product Activation

Windows Product Activation is missing.

Safe mode

The Safe mode is completely broken and results in a bugcheck with code 0x0000007B. This is because the Safeboot key, located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control is largely incomplete and missing a lot of entries. Restoring the key from an earlier build with working safe mode allows this build to boot properly, but the video driver will not initialize properly. As a result, the operating system will freeze as it transitions into graphical mode, so Safe Mode is currently not known to work on these pre-reset Longhorn componentized builds.
