It is the build given to attendees of Microsoft's Windows Hardware Engineering Conference 2004 in Seattle, Washington, held between 4–7 May, making it one of the only two pre-reset Longhorn builds that received a widespread release by Microsoft, the other being [[Windows Longhorn build 4051|build 4051]]. It is widely considered to be one of the most notable pre-reset builds of Longhorn. Having been released publicly, it is also one of the several Longhorn builds that has a [[timebomb]] set to evaluation mode that triggers after 180 days, and as such it can be installed on the current date. Once the timebomb is triggered, Windows immediately logs the user out and returns to the log on screen if the user tries to log on. ==New features and changes== === User profile picture === The user profile picture has been replaced with a silver variant from [[Windows Live Messenger|MSN Messenger]]. === "Leaves" wallpaper === The default wallpaper has been changed to "Leaves", which was first seen in [[Windows Longhorn build 4067 (private/lddm dev tech(davidmo))|build 4067 (private/lddm_dev_tech(davidmo)]], albeit without any text. === Desktop Window Manager and MIL === *This build, unlike many other leaked builds, is the first build to have complete Media Integration Layer (MIL) effects in Explorer and Internet Explorer from the [[Desktop Window Manager]], thanks to an early version of MILExplorer. However, a registry modification is required to extend the effect into the full UI of Explorer and Internet Explorer. The green translucent effect called "Jade" is used natively in this build instead of transparent "Glass". Further modifications such as a re-created <code>aero.msstyles</code> file is required to replace the Jade window frames with Glass ones. See the [[Windows Aero#Windows Longhorn builds 4074 to 4082|Windows Aero]] page for instructions on how to enable Aero effects. *This build also contains Aero Stars, an animated desktop which shows stars bouncing around the screen. It does not rely on DWM and therefore works with DWM disabled. Despite this, it is somewhat buggy and some graphic adapters may have trouble rendering it. See the [[Windows Aero#MIL Effects|Windows Aero]] page for instructions to enable. *An early version of Flip3D has been added to this build. It lacks animations and can be unstable at some time. Unlike post-reset builds, it uses the same key shortcut as the default window switcher, leaving the latter inaccessible with DWM enabled. <gallery> File:WindowsLonghorn-6.0.4074-AeroStars.png|Aero Stars File:Longhorn-4074-Flip3D.png|Flip3D </gallery> === Other Aero features=== The ability to control DWM through the {{key press|Ctrl|⇧ Shift|F9}} key combination (seen in internal builds) has been disabled at compile-time. === Preview Pane === *The Preview Pane has been overhauled in this build, after having been under construction in earlier builds, such as [[Windows Server 2008 build 4066|4066]]. There is a new button which acts as a toggle between the tasks pane and the details pane. Its height has also been diminished by default; expanding the Preview Pane will show more tasks. *The banners for libraries have been majorly uplifted. *This build contains an Animated Preview Pane Aurora but requires some modifications in the theme file to enable it.<ref>https://longhorn.ms/aurora-aero/</ref> <gallery> File:4074FolderPane.png|Default File:4074DocumentsPane.png|Documents File:4074PhotosPane.png|Photos File:4074MusicPane.png|Music File:4074GamesPane.png|Games File:4074ContactsPane.png|Contacts </gallery> === LDDM-exclusive boot screen === A unique boot screen intended for machines containing graphics cards that are compatible with the Longhorn Display Driver Model is present in this build, depicting a glass progress bar that switches between each color in the visible light spectrum, with compliments made towards the user fixed below it. The only resolution supported by this boot screen is 1024x768. As no LDDM-compatible graphics drivers are known to exist, the boot screen has not been made to work as of writing. === Help applications === Two unfinished Windows Help applications are hidden as <code>HelpPane.exe</code> and <code>hlplgvwr.exe</code>. * <code>HelpPane.exe</code> is an updated version of the one found in [[Windows Longhorn build 4039 (Lab06 n.030827-1717)|build 4039]]; it opens on the right side of the screen, shifting other open programs to the left. On the right there is an arrow button used to change the program to a normal window. Selecting "View all Tasks" from the Options menu presents the user with a list of general tasks, each containing a set of "folders" that correspond to different help topics. Most topics are unfinished. * <code>hlplgvwr.exe</code> appears to be an earlier version of the first app: it always opens as a normal window, lacks a button to send it to the right side and selecting "View all Tasks" simply opens a HelpPane window.<gallery> File:4074helppane1.png|HelpPane.exe File:4074helppane3.png|hlplgvwr.exe File:4074helppane2.png|Tasks in HelpPane.exe File:4074helppane4.png|A task </gallery> === Buddy Matchmaker=== "Play A Game With Friends" was renamed to Buddy Matchmaker. However, it will throw out errors unlike in other Longhorn builds such as [[Windows Longhorn build 4051|4051]] and [[Windows Longhorn build 4093|4093]]. <gallery> File:Longhorn 4074 Buddy Matchmaker.png|Buddy Matchmaker (Online Games) </gallery> ===New dialog boxes=== *A new program box has been added, saying that it is available and if the user really wants to change the access of the other program. *A new pre-release fallback box for drivers has been added. *A new application crash box has also been added. Albeit being similar to the pre-release fallback box, it has a debug button and different information. *A new error box has been added for Application Context exceptions. *The dialog box for when a program is not responding has been updated.<gallery> File:4074NewProgram.png|"A New Program Is Available" dialog File:Longhorn 4074 Driver Package Installation Error.png|Pre-release fallback warning File:4074applicationcrash.png|Application crash File:4074ace.png|Application Context Exception File:WindowsLonghorn-6.0.4074-NotResponding.png|"Not responding" dialog File:4074EndedProcess.png|Dialog after ending process </gallery> ===Other new features and changes=== *[[Windows Live Messenger|Windows Messenger]] has been updated to version 6.1, with a completely new interface. *A new driver installation system is implemented. As a result, most drivers that worked on [[Windows XP]] will often have the driver installation fall back to a "pre-release mechanism" upon installation. If a pop-up notifying about the pre-release mechanism appears, simply press cancel. *Internet Information Services has been updated, but in Windows Components Wizard it says that is version 7.0, but after installation it claims to be version 6.5. *The copyright date in <code>[[winver.exe]]</code> has been updated from 1985–2003 to 1985–2004. * This build improves support for Intel x64 processors with the EM64T instruction set. The previous x64 build, [[Windows Longhorn build 4051|4051]], was unable to boot on those processors. *The new scheduled tasks were also implemented, which they might have lots of empty content and some pages might not be functional at all. * A hidden Speech Recognition application has been added and can be run under <code>C:\Program Files\Common Files\Microsoft Shared\Speech\stsserver.exe</code>. * An unfinished volume flyout is accessible under <code>SndVolFlyout.exe</code>. It has three options which are invisible unless hovering over them: "My Audio Devices" (opens Hardware and Devices), "Audio Video Preferences" (opens sound options applet) and "Reset Volume Defaults".<gallery> File:Longhorn 4074 Windows Messenger.png|Windows Messenger File:4074volcontrol.png|alt=This application was supposed to be a flyout as mentioned in the application name|Volume Control (<code>SndVolFlyout.exe</code>) File:4074VolumeControlOptions.png|Composite image showing hidden options and possible size File:4074nst.png|New Scheduled Tasks (<code>jobfldr.exe</code>) File:4074schedtask.png|Schedule Task (<code>jobppage.exe</code>) File:Longhorn 4074 Sticky Notes.png|Sticky Notes File:Longhorn 4074 Speech Recognition.png|Speech Recognition </gallery> It is worth to note that features related to .NET Framework, such as the sidebar, MIL effects or Aurora, do not work on the x64 version. Basic DWM functionality is present, but can be enabled by directly calling relevant <code>uxdesk.dll</code> exports using <code>rundll32</code> and a command prompt or extracting <code>sbctl.exe</code> from the installation media. ==Bugs and quirks== ===Installation=== *This build cannot be normally upgraded from a previous build, and as such it can only be clean installed. *The Checked/Debug compile of the x86 version requires either a debugger or replacing drivers with ones from the non-Checked/Debug versions of this build due to the large amount of assert errors that prevents setup from installing the system properly. *Setup might disallow installation on IDE drives if SCSI drives are installed in the system. However, this seems to be hardware specific. *When the text mode setup on some hardware configurations reboots, if the disk drive is set to IDE and the disk drive controller is set to SCSI an <code>Error loading operating system</code> message will appear. *The Checked/Debug compile of the x64 version has an assertion error in the IDE driver that results in a [[bugcheck]] during "Completing installation" phase with an error code of <code>0x0000001E</code> and <code>0xFFFFFFFF80000003</code> as there was no kernel debugger attached at that point. When this occurs, start WinDbg on the host, connect the debugger to the VM's virtual serial port (shut down the VM then add and configure one if there are none in the VM), then restart the VM and press the F8 key to select "Debugging Mode" and continue the setup. Once the "Assertion failed" message appears, type "ignore" or the letter I to the debugger command window. Repeat this on every message until the setup finishes. *This build's [[Windows Preinstallation Environment|WinPE]] setup takes a very long time (about 2–3 minutes) to boot and has a chance to temporarily freeze for a short amount of time. This can be fixed by pressing F5 and then select Standard PC. ===Broken PS/2 mouse driver in Preinstallation Environment=== The PS/2 mouse driver is broken in this build's Preinstallation Environment, so a keyboard is required to navigate in the WinPE. This bug doesn't occur if using an USB mouse. ===System sounds=== Many system sounds do not work as they are pointed to the <code>Windows</code> directory instead of the <code>Windows\Media</code> directory. Even if the registry entry is modified to point to the Media directory, the sounds often do not work for unknown reasons. === Desktop === *Showing hidden folders leads to a Search icon and a [[Help and Support Center]] icon appearing on the desktop. If the icons are removed from the Desktop namespace via registry editing, both aforementioned features would no longer be accessible. *Holding {{Key press|⇧ Shift}} while right clicking on the desktop shows View options like Windows Explorer. Multiple views for the desktop can be selected, but it often results in display glitches or completely breaking the desktop.{{efn|This menu is used to enable the Aurora desktop background in some pre-reset builds like build [[Windows Server 2008 build 4066|4066]] or earlier.}} *If Aero Stars is enabled, the icons on the desktop will disappear. *Desktop icons tend to change their vertical spacing quite a lot even if icons are not being auto arranged. The Recycle Bin icon jumps randomly on the desktop as well and sorting options are not saved between reboots. The desktop has also been reported to rearrange other icons automatically in certain cases. ====Themes==== *Changing themes might cause the theme service to malfunction, causing the taskbar to have the [[Windows Classic|classic theme]] visuals, and the start menu possibly being entirely black. Restarting the Themes and Desktop Manager service in <code>services.msc</code> or switch to the Windows Classic theme and then revert to [[Luna]], [[Slate]], or [[Jade]] themes will resolves the problem. It can also cause [[File Explorer]] failing to render entirely. Terminating <code>explorer.exe</code> sometimes fix it, otherwise the user will need to restart the system. *[[DWM]] works with most of the existing visual styles, causing visual glitches especially when using the Classic theme, which usually crashes Explorer itself. *On some configurations with the Slate theme applied, the window title may be displayed in incorrect font. * The [[Slate]] theme has its start button low-quality stretched if the [[Windows Sidebar|sidebar]] is enabled, and the hitbox of it and the [[Aero]] theme does not reach all the way to the corner. ====Composition==== *Performance might suffer greatly when [[DWM]] is running, even on fast computers. *Sometimes, Explorer windows with MIL effects may display the text overlapped. *When enabling DWM when using a visual style other than Jade (such as Slate), the DWM window frame resource in <code>desksrv.dll</code> is used due to the absence of the <code>STREAM</code> folder in all visual styles files except [[Jade]], which makes the system uses the less transparent border in <code>desksrv.dll</code> (possibly due to limitations) compared to the borders in the Jade visual style, which is much more transparent. This quirk is also present in [[Windows Server 2008 build 4066|build 4066]]. **However, when turning off DWM and then turn it back on, <code>desksrv.dll</code>'s border will be always used in next DWM enable attempts even when the [[Jade]] visual style is used. A workaround is to restart the theme service. *Incorrect scaling happens when using the [[Windows Classic]] theme with large fonts with DWM turned on. *Upon choosing a wallpaper, the desktop will glitch out if DWM is on. *There is a chance for the screen to flash repeatedly when turning on DWM, which renders the system unusable. *[[Windows Media Player]] 9's automatic hiding of the system frame does not work with DWM. The user will not be able to open or close the player or click on any menu until the user presses {{key press|Ctrl|M}} key to show menu bar and then reopen Windows Media Player. *The title bar text will not update when under normal use with DWM turned on unless the user maximizes or restores down the window. *The Basket sidebar tile leads to an Explorer crash loop if a DWM theme is used. The only solution is to remove the tile from the registry. * Using DWM increases the chance of Explorer crashing under normal use. There is a chance that Explorer won't load properly and instead the system would suffer tremendous lag requiring the user to hard reset the machine. *This build (and other builds onwards) does include transparent glass notification UI, activated when turning on DWM. However, unlike [[Windows Longhorn build 4066|build 4066]], this build does not render it correctly, as a black background appears behind them. An assembly named <code>System.Windows.Explorer.dll</code> must be patched for the transparent glass notification UI to render correctly. ===Creating folders=== The option to create folders by right-clicking and selecting New does not work as the Folder entry is missing. Apply the following registry key to fix this problem: <syntaxhighlight lang="registry"> Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.Folder] @="Folder" </syntaxhighlight> ===Memory leak=== *As with most later Longhorn builds, this build's Explorer tends to leak memory after a while. Turning off the Sidebar reduces the effect of the memory leak. * WinFS and related services are also affected by major memory leaks. Disabling WinFS solves the problem. ===WinFS=== [[WinFS]] functionality is not enabled by default on this build. To enable WinFS, the user must set the startup type of the following services to ''Automatic'': *SAM WinFS Account Store *Computer Data Synchronization Manager Programs that are dependent on WinFS (such as Outlook Express) may crash if the services listed above are not enabled or running. ===Faulty file browse UI=== The Explorer file browse UI has two noticeable bugs. The first being that the Navigation Bar only allows for navigation by clicking on parent directories in the bar. The second being that the Filter and Preview panes may occasionally appear black or show parts of content behind the window, and the chance increases when [[Desktop Window Manager|DWM]] is turned on. ===Safe mode=== Windows Explorer crashes in a loop by default under [[safe mode]] since the sidebar tiles are enabled by default. A prompt will appear titled "Desktop" and will ask to proceed to work in safe mode or start System Restore. Clicking either button will not perform any action and will bring up another exact prompt instead. The desktop will not appear with the prompt and Explorer may not launch. The only workaround is to remove all the sidebar tiles from the registry: #Open the [[Registry Editor]] from Safe Mode with Command Prompt. #Navigate to <code>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Sidebar\Tiles</code>. #Collapse the "Tiles" folder, and then remove all the sidebar tiles from the registry. #Type in <code>explorer</code> in the Command Prompt. Once done, <code>explorer.exe</code> will start in Safe Mode. Additionally, when Windows Explorer is running in safe mode, clicking on Log Off from the start menu or initializing the shut down dialog box via {{key press|Alt|F4}} on the desktop with safe mode will bring up another exact prompt. To log off, shut down, or restart, press the {{key press|Ctrl|Alt|Del}} key and then click on "Log Off", "Shut Down", or the ">" button for more options. ==== Other bugs ==== The Hardware and Devices folder is empty in Safe Mode. ===[[Internet Explorer]] === *The built-in download manager does not work, which leads to downloads not working at all. *Many websites hang under Internet Explorer even if they work under older versions of the browser. *The website URL is displayed as white by default which is difficult to read under the Slate and Jade themes. ===Sticky Notes=== This build includes a [[Sticky Notes]] app similar to the one found in build [[Windows Longhorn build 4042 (Lab06 n)|4042 (Lab06_n)]], but it fails to start because of a missing DLL, namely <code>stickynotebubble.dll</code>. This missing DLL can be found in the <code>\build\filerepository</code> folder of the build [[Windows Longhorn build 4081|4081]] installation disc. Copying the aforementioned DLL into the same directory of the <code>StickyNote.exe</code> file found in the <code>\WINDOWS\Microsoft.NET\Windows\v6.0.4030</code> folder and typing in Run dialog <code>%windir℅\WINDOWS\Microsoft.NET\Windows\v6.0.4030\StickyNote.exe /new</code>, will launch Sticky Notes. ===AutoPlay=== There are some noticeable bugs that user can encounter with the AutoPlay dialog: *The [[DirectX]] spinning icon animation of the prompt might spin too fast on newer hardware. *The icon on the title of the prompt might have a black box as background when the icon is not rectangular. ===Parental Controls=== Parental Controls are not functional in the x64 version of this build and returns a Visual C++ runtime error. === Other bugs=== * DNS requests might not work properly on certain network configurations when a DNS server is automatically acquired via DHCP. Configuring DNS manually fixes this problem. *On some multi-core configurations and at random times, Windows hangs significantly rendering the operating system almost unusable a few seconds after logging in. The only solution is a hard reset. *This build relies on Terminal Services and the User Profile Service to properly log users on. If Terminal Services are disabled or set to manual, the operating system hangs at a black screen with the [[watermark]]. If the User Profile Service is disabled or set to manual, the user will be able to logon, but Explorer would not be able to load properly, and profile specific settings would be lost. *Some services cause this build to hang at the logon screen for about one minute, which is unrelated to the {{key press|Ctrl|Alt|Del}} requirement. *Pressing {{key press|Ctrl|Alt|Del}} at the login prompt (when it is required/enabled) has a chance to either hang the system or cause a <code>0x00000050</code> or <code>0x0000008E</code> bugcheck. This chance increases the more users have logged on and off and Disabling Fast User Switching. *If a contact is pinned to the sidebar, an error message would be displayed on certain occasions that the contact cannot be updated. This error can be safely ignored. *Edits made to certain Explorer features such as the top bar are valid only for the open window and do not persist, even for the same folder. *Sometimes, inserting CD and DVD discs has a chance of crashing with <code>UDF_FILE_SYSTEM</code>. *Sometimes, while booting to the desktop, there is a chance of crashing with <code>0x000000D1</code>. === Itanium build specifics === The IA-64 compile also contains all of the bugs and quirks from the x86 compile. However, there are some notable exceptions: *Because this build architecture lacks WinFS, applications dependent on the framework (such as Outlook Express), alongside with WinFS-provided virtual folders/libraries, do not function. WinFS-related folders can be removed from the Computer system folder by editing registry entries. *Due to the heavier nature of 64-bit binaries, Explorer will consume a copious amount of memory right after logging in, even with advanced features such as the Sidebar disabled. *Certain graphics drivers may cause performance degradation when .NET features (such as the sidebar) are enabled. *Explorer works properly in safe mode, unlike its x86/x64 variants. Clicking Yes on the safe mode information dialog dismisses it, and Explorer starts normally. * Upgrading to this build will result in Setup failing to properly configure the system registry and NVRAM boot entries. If installing over a previous build, the hard disk must be completely wiped and the system's EFI firmware cleared of previously created Windows boot entries, as the build will not boot due to an NVRAM-related error. Entries and dual-boot installations on separate partitions created by later versions of Windows (such as [[Windows Server 2008 R2]]) may be left alone. * Explorer may randomly crash when opening folders with a <code>Fatal Execution Engine Error</code>. * Opening DirectX Diagnostics (or using any DirectX-using feature including the AutoPlay prompt) after changing display resolution will hang the system. == Gallery == === [[Windows Setup]] === <gallery> File:4074 Setup.png|Autorun File:4074 ProductKey.png|Product key entry File:4074 EULA.png|End-user license agreement File:4074 CleanInstallSummary.png|Clean install summary File:4074 DiskPartitioning.png|Disk partitioning File:4074 PCname.png|Computer name File:4074 copying files.png|File copy File:4074 detecting hardware.png|Hardware setup </gallery> === Interface === <gallery> File:Longhorn40424093Boot.png|Boot screen (XPDM) File:4074-HiddenBootScreen.png|Boot screen (LDDM) File:Windows Longhorn Build 4074-2018-11-06-19-34-04.png|Login screen File:WindowsLonghorn4074NoSidebar.png|Desktop without sidebar File:LH4074-WorkingSafeMode.png|Safe mode (with all required Sidebar tiles disabled) File:WindowsLonghorn-6.0.4074-x64ParentalControlsBug.png|x64 Parental Controls bug File:SafeLonghorn.PNG|Safe to shutdown screen </gallery> ===Applications and Features=== <gallery> File:Longhorn 4074 Games Folder.png|Games folder File:4074ContactProperties.png|Contact details File:Longhorn 4074 Autorun.png|Autorun prompt File:Longhorn 4074 Rules and Alerts.png|Rules and Alerts File:4074 Power Sidebar Flyout.png|Power Sidebar Flyout File:4074PictureViewer.png|Windows Picture Viewer File:Longhorn 4074 Help and Support Center.png|Help and Support Center File:4074mgutw.png|Games Task Wizard (<code>mgutw.exe</code>) </gallery> ===Themes=== <gallery> File:WindowsLonghorn-6.0.4074m7-blstartmenu.png|Blue Luna theme File:WindowsLonghorn-6.0.4074m7-oglstartmenu.png|Olive-Green Luna theme File:WindowsLonghorn-6.0.4074m7-slstartmenu.png|Silver Luna theme File:WindowsLonghorn-6.0.4074m7-wcstartmenu.png|Windows Classic theme File:WindowsLonghorn-6.0.4074m7-sstartmenu.png|Slate theme File:WindowsLonghorn-6.0.4074m7-jstartmenu.png|Jade theme </gallery> === DWM themes === This build of Longhorn includes 2 types of DWM themes - Aero and non-Aero.
