Windows Longhorn build 4030 (Lab06 n.030702-1727)

Windows Longhorn build 4030 (Lab06_n.030702-1727) is a Milestone 6 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 BetaArchive's FTP server, and was released in the tenth set of his 33 Longhorn/Vista builds on 2 February 2020https://www.betaarchive.com/forum/viewtopic.php?t=40726. 
== New features and changes ==
=== Longhorn Help Place===
The Longhorn Help Place is now functional. Once opened, the help place welcomes the user, and asks them on how they can help them.
From that point, the user can search for answers (which actually just opens a search window with the inputted content), or view the latest vulnerability patches. A very low quality Windows XP flag is also present in the header.
== Bugs and quirks ==
=== General ===
The Sidebar is minimized on first boot.
=== Desktop Compositing Engine ===
While the Desktop Compositing Engine functions correctly, Direct3D shaders are not enabled due to a bug. As the DCE window frames rely on these shaders to function, it is not possible to enable them in this build.
=== Autorun ===
Under some circumstances, the Autorun program may display the incorrect text.

Windows Longhorn build 4031 (Lab06 n)

Windows Longhorn build 4031 (Lab06_n) is a Milestone 6 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 BetaArchive's FTP server, and was released in the ninth set of his 33 Longhorn/Vista builds on 1 February 2020, alongside the main lab compile of 4085, the x86 version of 4083, the main lab compile of this build, its Lab07 Server counterpart and build 5520.
== Bugs ==

On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to BetaArchive's FTP server, and was released in the ninth set of his 33 Longhorn/Vista builds on 1 February 2020, alongside the main lab compile of 4085, the x86 version of 4083, the Lab06_n compile of this build, its Lab07 Server counterpart and build 5520.
As this build was compiled after the lab06_n compile of build 4029, the "File a Longhorn Bug" shortcut is present on the desktop.
== Bugs and quirks ==
As the computer imaging this build's WIM bugchecked with the code 0x1000008e (KERNEL_MODE_EXCEPTION_NOT_HANDLED_M) caused by ataport.sys, upon logging in, the error message "The system has recovered from a serious error" will appear. This is due to the fact that the crash has not been cleared prior to imaging.

Windows Longhorn build 4032

Windows Longhorn build 4032 is a Milestone 6 build of Windows Longhorn, which was uploaded to BetaArchive's FTP server on 3 December 2018, along with build 4020. Prior to its publication, a screenshot of the build was shared on the aforementioned community's Discord server on 27 November 2018.
== Changes ==
=== Login process ===
This build's login process has been updated to boot up faster when compared to previous builds, although this breaks safe mode in the process.
=== Services ===
The Discovery Persistence Service has been introduced. Human Interface Device Access has also been renamed to HID Input Service.
==Bugs and quirks==
===Installation===
Most copies of this build's installation media are not bootable due to corruption.
===Desktop Compositing Engine===
While the Desktop Compositing Engine functions correctly, Direct3D shaders are not enabled due to a bug. As the DCE window frames rely on these shaders to function, it is not possible to enable them in this build.
===Safe mode===
By default, it is not possible to login while in Safe mode. Due to the login process change, the "User Profiles Service" and "Group Policy Service" are required to access the login page and perform the login process respectively. Because these services are not configured by default to start within Safe mode, this results in logonui.exe showing the error "There are no more endpoints available from the endpoint mapper" on the login screen and failing to show available user accounts.
These services can be enabled to function in safe mode by adding the following entries to the service whitelists in the registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\ProfSvc]
@="Service"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\GPSvc]

Windows Longhorn build 4033 (idx01)

Windows Longhorn build 4033 (idx01) is a Milestone 6 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 BetaArchive's FTP server, and was released in the sixth set of his 33 Longhorn/Vista builds on 29 January 2020, alongside Windows Vista build 5487.https://www.betaarchive.com/forum/viewtopic.php?t=40726 This build is currently only available in the IA-64 architecture.
This build was compiled in evaluation mode and can be installed on the current date. Attempting to log onto the desktop once the timebomb has been triggered will return the user to the login screen.
== Bugs and quirks ==
=== Desktop Compositing Engine ===
While the Desktop Compositing Engine functions correctly, Direct3D shaders are not enabled due to a bug. As the DCE window frames rely on these shaders to function, it is not possible to enable them in this build.
=== File Explorer ===
* Searching and cut/copy-pasting is not functional, as attempting to do so will cause an explorer.exe crash.
* WinFS is not present. Thus, applications relying on it, such as Outlook Express will crash upon launching.
* The USB Mass Storage feature is non-functional.
* The file saving dialog is non-functional.
=== TCP/IP bug ===
The TCP/IP stack is very unstable and can often crash.
=== Windows Product Activation ===
Windows Product Activation is missing.

Windows Longhorn build 4039 (Lab06 n.030827-1717)

Windows Longhorn build 4039 (Lab06_n.030827-1717) is a Milestone 6 build of Windows Longhorn, which was shared online on 22 August 2007.https://www.betaarchive.com/forum/viewtopic.php?t=2436
==NFO file==
==New features and changes==
===User interface ===
The default Administrator user account now uses a silver MSN Messenger profile picture.
==Bugs and quirks==
===Desktop Compositing Engine===
Unlike its previous compile, the Desktop Compositing Engine in this build is incredibly unstable and can hang after just a couple of seconds.
===Safe mode===
By default, it is not possible to login while in Safe mode. Due to the login process change made in build 4032, the "User Profiles Service" and "Group Policy Service" are required to access the login page and perform the login process respectively. Because these services are not configured by default to start within Safe mode, this results in logonui.exe showing the error "There are no more endpoints available from the endpoint mapper" on the login screen and failing to show available user accounts.
These services can be enabled to function in safe mode by adding the following entries to the service whitelists in the registry:
Windows Registry Editor Version 5.00

Windows Longhorn build 4040

Windows Longhorn build 4040 is one of the last Milestone 6 builds of Windows Longhorn. On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to BetaArchive's FTP server, and was released on 31 January 2020, alongside build 4002 and build 5356. Prior to its publication, this build was shown off on the previously mentioned blog.
It is one of the last builds to contain the Plex theme.
==New features and changes==
The entirety of the user interface remains nearly identical to that of build 4038, due to Lab04's notable use of older code. This can be seen throughout the operating system, such as in the File Explorer, the Desktop Compositing Engine (it still has the same rendering bug as build 4038) or on the Sidebar Clock tile.
===Setup ===
While the Setup is identical to previous builds, the clock and numeral sprites no longer utilize a transparent background.
==Bugs and quirks==
===Installation===
Most copies of this build's installation media cannot be booted from the CD due to a call to a non-existent index in the INSTALL.WIM file by SETUPLDR.BIN.
===Safe mode===
By default, it is not possible to login while in Safe mode. Due to the login process change done in build 4032, the "User Profiles Service" and "Group Policy Service" are required to access the login page and perform the login process respectively. Because these services are not configured by default to start within Safe mode, this results in logonui.exe showing the error "There are no more endpoints available from the endpoint mapper" on the login screen and failing to show available user accounts.
These services can be enabled to function in safe mode by adding the following entries to the service whitelists in the registry:

Windows Longhorn build 4042 (main)

Windows Longhorn build 4042 (main) is one of the last Milestone 6 builds of Windows Longhorn. It was compiled four days prior to its Lab06_n compile. 
On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to BetaArchive's FTP server, and was released in the twelfth and final set of his 33 Longhorn/Vista builds on 4 February 2020 along with build 4082, build 4087 and build 5492. Prior to its publication, this build was shown off on the previously mentioned blog.
This is the last build to contain the Plex theme and the Pig Latin build tag strings.
Similiarly to build 4040, many aspects of the user interface remain identical to build 4038.
==Fixes==
Safe mode now functions as intended, as the "User Profiles Service" and "Group Policy Service" services are now enabled by default in safe mode after the login process change done in build 4032.

Windows Longhorn build 4044

Windows Longhorn build 4044 is an unleaked Milestone 7 build of Windows Longhorn. This build uses a different winver branding which is seen in later builds, up to Windows Vista build 5215 in Professional edition and Windows Vista build 5310 in Starter edition. This build was first seen in a screenshot at PDC 2003 during the Avalon Graphics and Media (Part 2) presentation: Using Graphics, Animation and Composition in Your Applications session (CLI341) by Greg Schechter to demonstrate the power of XAML in Windows. Since then, a couple more screenshots of this build have been leaked.
