Windows Longhorn build 4011 is a Milestone 4 build of Windows Longhorn, which was shared online on 21 July 2006.[1]

New features and changes[edit | edit source]

Setup[edit | edit source]

Product key characters are now uppercase, along with dashes now being added every five letters.

After partitioning the disk, Setup now asks the user to set a computer name.

Boot screen[edit | edit source]

A new boot screen has been introduced, which features the Longhorn logo and wordmark along with the Windows XP progressbar.

User interface[edit | edit source]

Notifications[edit | edit source]

Notifications now contain a close button, no longer requiring the user to wait until the notification expires.

Sidebar[edit | edit source]

Nearly all sidebar tiles were updated and no longer require a registry modification to appear.

Search now features a search bar, along with a My Stuff button, where the user can search for their files, help & tasks, contacts or internet queries.

The Windows Media Player tile has been updated, featuring new control buttons, information about the song currently being played and a playlist function. However, these features are not known to work, as attempting to open a file will result in a MediaUXSrv.exe crash, followed by an Explorer crash, rendering the tile unusable.

A new Synchronize tile was added, which automatically synchronizes the data on the user's computer with the data on the network.

The Quick Launch, Most Frequent Apps and User tiles have been shrunk down to match the content inside of them.

The Set sidebar & taskbar side options located in the sidebar context menu have been replaced with a Bar Settings option. This option opens an Avalon-based app where the user can select a pre-configured sidebar and taskbar setup, or their own configuration.

Tiles now also fade in and fade out when being added or removed.

Windows Explorer[edit | edit source]

The task view pane has been updated to feature a gray to blue gradient when viewing My Computer or the Control Panel in Classic View. The pane itself now features three documents in the background, along with a counter specifying how many items are in the currently viewed folder. The icon of the currently selected file, drive or folder is now also shown.

This is the earliest currently available build to contain 3D View, a feature that animates the desktop background and icons. It can be enabled by holding down the ⇧ Shift key, right clicking on a part of the desktop, selecting View and then enabling 3D View. When enabled, the wallpaper will animate and icons will spin around while being hovered over.

Control Panel[edit | edit source]

Icon difference between 4008 (left) and 4011 (right)

The Parental Controls icon was updated to represent a parent and two children.

Desktop Compositing Engine[edit | edit source]

Unlike build 4008, the Desktop Compositing Engine now functions. However, it only provides transparency effects.

Miscellaneous[edit | edit source]

The copyright date seen in the winver.exe banner has been updated to read 1985-2003 instead of 1985-2006.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

  • Many widely available copies of this build contain a corrupted version of the install.wim file, resulting in an improper installation. Some copies can install properly, though all long filenames in the winsxs folder of their WinPE got truncated when the ISO was created, resulting in Setup not being able to load its desired components, leading to debug assertion errors.
  • This build's Preinstallation Environment can cause a win32k.sys crash after the partitioning page and thus crash. As such, to install this build, a Windows PE from a different build must be used.
  • Attempting to launch the Command Prompt via ⇧ Shift+F10 in this build's WinPE will trigger a bugcheck with error code 0x0000008E (KERNEL_MODE_EXCEPTION_NOT_HANDLED).
  • The out-of-box experience crashes after selecting Next on the first page.

General[edit | edit source]

The sidebar will fail to render properly when adjusting the resolution.

Windows Explorer[edit | edit source]

Icons become gradually more pixelated when scrolling.

Themes[edit | edit source]

The Luna theme uses the Arial font in most places rather than Trebuchet MS or Tahoma..

Miscellaneous[edit | edit source]

Windows Storage Engine often crashes on startup.
