Windows Server 2008 build 4066
|Build of Windows Server 2008|
|Timebomb||2004-08-24 (+180 days)|
Windows Server 2008 build 4066 is a build of Windows Server 2008, which was originally described by Grabberslasher in his UX.Unleaked blog entry on 1 May 2008 and was later uploaded to BetaArchive on 20 December 2008.
It is the fourth and last available server build based on the pre-reset code, the others being builds 4028, 4031 and 4038. In a similar fashion to builds 4031 and 4038, this build uses the older i386 installation method.
New features and changes[edit | edit source]
Several features, which have been previously stripped off the code of the main branch by the time build 4051 was released, have been added back, together with many other new ones, some of which have been previously seen in builds demonstrated by Microsoft, such as the famous, unleaked 4050 one. Among these:
- Many sidebar tiles, including Basket, News Feed, Notification History, Search, Sync, Windows Media Player and Windows Media Status. The Clock tile is now pinned at the bottom of the Sidebar, and there is also a hidden Sticky Notes tile, similar to the one found in build 4074.
- The look of the notifications has changed, as they no longer use a background color that fits the Slate theme. Moreover, they seem to be buggy as the icons on the left do not have a reflection.
- Several view modes, including "3D View" and two new ones respectively called "MIL View" and "Listview Spy". The last one can be enabled, together with the "Carousel" and "Panorama" options, by merging the entries below into the registry:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer] "Carousel"=dword:00000001 "LVSpy"=dword:00000001 "Panorama"=dword:00000001
- The preview pane has changed compared to build 4053: tasks have been temporarily removed, and a button which acts like a toggle between the unfinished task pane and the details pane has been added.
- Filtering within WinFS libraries has been enhanced: the most generic filters can be found by expanding "Document Favorites", meanwhile more detailed filters are available by expanding "Properties".
- The "Import Contacts" wizard has received a makeover and it is now consistent with the overall look of the Aero wizards.
- Several new items can be found in the "File" menu of the Games library, from which a new Default Game Patching Options dialog can be launched.
- A new Sharing wizard has been added, although there is an option to use the older "Sharing" tab.
- The new Windows Media Player application has been greatly enhanced compared to the one found in build 4053, and it can be run by executing
floatingPlayer.exe, found in the
WINDOWSdirectory. It should also be noted that Windows Media Player 9 is disabled by default.
- Sticky Notes, although no one has been able to get them to work, as of now.
- New high-resolution icons, which replaced several icons that originated from Windows XP.
Desktop Window Manager (DWM)[edit | edit source]
The Desktop Window Manager has been reintegrated into the code of the main branch after being absent from builds ranging from 4048 to 4053, and can now be toggled by pressing Ctrl+⇧ Shift+F9, or running
rundll32 uxdesk.dll, DwmStartComposition.
A blur effect can be seen behind the taskbar and the sidebar when they are using Aero resources, but seems to be absent behind certain types of windows, unlike in build 4074.
It should be noted that two versions of the frames used by DWM exist within the system: a less transparent one, stored in
desksrv.dll and loaded by default when using the Slate theme; and a more transparent one, stored in the
STREAM folder of
jade.msstyles and loaded by default when using the Jade theme. After having turned DWM off, the next time it will be enabled it will use the less transparent frames found in
desksrv.dll regardless of the theme used. After re-applying Jade theme or restarting theme service, DWM will use borders from
This build features an earlier and buggy version of the extended glass frames seen in build 4074, and it is possible to enable them via the same
MILExplorer DWORD. Most of the times the extended glass frame will be displayed as a black solid color, other than making the navigation buttons and the address bar disappear or completely hiding the contents of folder. For getting extended Glass effects to work, at least one Explorer window has to be opened before DWM is started, and those effects cannot be applied if Explorer window is opened after DWM is started.
This is also the only available build able to render transparent notifications properly when DWM is enabled, as from build 4074 onwards a black solid color background appears behind them. It is possible to get transparent notifications to work in builds ranging from 4074 to 4093 as well, but a modified
System.Windows.Explorer.dll file is required.
Last but not least, it is possible to enable what is commonly referred to as "Aero Stars" by setting up a
MILDesktop DWORD, once again, like in build 4074. Disable the sidebar, unlock the taskbar and then merge the below values into the registry:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer] "MILDesktop"=dword:00000001

The resources for the Aero taskbar and sidebar are present, but they cannot be normally used because the build is hardcoded to use the Slate ones. A modified version of the
Microsoft.Windows.WCPClient.dll assembly is required in order to load the Aero resources. Once loaded, it can be seen how a bug makes the sidebar tiles draw the background of the sidebar a second time. It is also worthy of noticing how the text of the taskbar buttons shifts between black and white, depending on whether a window is in its normal or maximized state, in a similar fashion to the unleaked build 4050. Unlike in build 4074, it is not necessary to set up the
MILExplorer DWORD in order to get the transparent taskbar and sidebar; instead, DWM has to be started while Explorer is running and sidebar is enabled.
Other Aero resources[edit | edit source]
Along with Aero taskbar and sidebar resources, this build includes resources for Aero clock and Aero preview pane image resources plus gradients, which would be included, but never used in later pre-reset builds, thus also requires modifying
Bugs and quirks[edit | edit source]
SKU[edit | edit source]
This build's SKU oddly identifies itself in branding as Standard Server, while the true one being Enterprise Server.
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
- Collapse the "Tiles" folder, and then remove all the sidebar tiles from the registry.
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 Alt+F4 on the desktop with Safe Mode, it will bring up another exact prompt. So to log off, shut down, or restart, press the Ctrl+Alt+Del key and then click on "Log Off", "Shut Down", or the ">" button for more options.
Ripe Field wallpaper[edit | edit source]
This build does actually include the same wallpaper which is used by default in Longhorn builds ranging from 4042 to 4067, although it is in JPEG format rather than BMP, and it is not installed by default. It is present in the
I386 folder of the installation disc, under the file name of
Windows Explorer[edit | edit source]
Windows Explorer ends up hanging and subsequently crashing pretty often in this build, most of the time when navigating between folders. Should this happen, make sure to kill the
dw20.exe process from the Task Manager and then proceed to restart
Sidebar[edit | edit source]
It should be noted that the Basket, Contacts and Sync tiles do not work, the latter making
explorer.exe enter a crash loop: removing the tile via the registry is the only solution to solve the aforementioned problem. Moreover, tile flyouts do not work in this build, as clicking any tile ends up restarting Windows Explorer.
[edit | edit source]
The Slate theme has its start button not displaying properly if the sidebar is enabled. This causes the start button to be less soft than in build 4042 to build 4053, and the hitbox does not reach all the way to the corner.
Installation[edit | edit source]
- On some computers and virtual machine configurations:
- Setup might not be able to format the drive. If this happens, an "Unknown Hard Error" bugcheck will occur.
PAGE_FAULT_IN_NONPAGED_AREAbugcheck might trigger after the first phase of the installation ends, thus the installation cannot continue. Reducing the virtual machine memory to 512 MB or less might solve the problem.
- The second phase of the installation can take a long time to complete and is extremely unstable.
- Some drivers may fail to install.
- The title for every Setup Wizard's stage freezes at Regional and Language Options, or Installing Devices if the user presses the ⇧ Shift+F11 keys to invoke the installation progress window.
Upgrade[edit | edit source]
- In order to upgrade to this build from build 4031, you must edit
dosnet.infin the i386 folder to
ProductType = 5. Then you must replace the following files and directories with copies from the RTM build of Windows Server 2003:
- If upgrading to this build, you will need to ensure that you delete
system32\drivers. Leaving this file will cause a
REGISTRY_ERRORbugcheck relating to this file, and rebooting will corrupt the registry, making it impossible to reboot back into setup.
- On some machines, the user will get stuck at the login screen as the user is unable to press Ctrl+Alt+Del. To fix this:
- Boot into Safe Mode.
- Load up Task Manager.
- Go to file > New Task.
- Type in gpedit.msc
- Go to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
Interactive Logon: Do not require CTRL+ALT+DELand change it to enabled.
- Reboot the machine.
- Logging in to this build may take several minutes after an upgrade.
- There is a chance that setup could fail during an upgrade as
Avalon Movie Maker[edit | edit source]
This build does include the Avalon-based Movie Maker. However, it is not functional and opening it will result in multiple assertion errors.
New Sharing Wizard[edit | edit source]
There is a typo on the "Who do you want to share the folder(s) with" text on the first page where it displays "Whom" instead of "Who"
