Windows Vista build 5048

Windows "Longhorn" build 5048 is the first pre-Beta 1 build of Windows Vista to leak after the development reset of Windows Longhorn. This build was released to attendants of WinHEC 2005, and was known as the "Longhorn Developer Preview". It calls itself Beta 1 in the setup handle, but it's not the true Beta 1.

Being a pre-beta 1 build, it is noticeably closer to Windows XP and Windows Server 2003 than to pre-reset builds. It is also an idx02 build, which suggest that it was recompiled several times, and therefore is behind regular builds compiled at the time. The x64 version of this build is similar to the x86 build, but it has a different EULA and Windows XP x64 Edition brand wallpaper instead of the Windows Server 2003 brand wallpaper which is named as.

Setup
Although previous builds of Vista re-used the older i386 installation process, this build re-uses the Windows Preinstallation Environment installation process from later builds of Longhorn, retaining the slate theme as well. However, a few changes have been made. The launching WinPE screen does not show anymore, now leaving you without any option of pressing F6 to load in certain drivers. The starting setup screen has also been majorly uplifted, now containing the windows flag. Anti-aliasing is no longer present on fonts, and the numbers on the progress bar no longer glow. Finally, the hardware portion of setup now includes a dummy progress bar on the bottom (all it does is just continuously increase in size until it reaches the end, then it goes back to the start), and the Windows flag has been added to the middle of the page. Asides from all of these minor changes, setup is overall mostly similar to what was found in later pre-reset builds of Longhorn.

Start Menu

 * Start Menu received many new updates in this build including the famous search box that will later be seen in Windows Vista and Windows 7, and the outlining of the start menu being transparent.
 * "All Programs" menu is now an inline menu and it doesn't open in a separate context menu-like UI.
 * "Turn off computer" is renamed into "Shut Down".
 * New icons for Shut Down and Log Off buttons.
 * User picture is removed (it will return in Windows Vista build 5098).

AERO (Authentic, Energetic, Reflective and Open)

 * This build includes three new Aero themes.
 * One of the new Aero themes (Theme 2) use a similar design to later builds of Vista (The only difference is that the minimize and maximize buttons are little arrows, minimize arrow points down and maximize arrow points up, but other than that, its basically the same.)
 * Aero theme is now the default theme overall system, along with its visual effects and wizards.
 * This build also has a new wallpaper and some Vista-like interface areas.

Desktop Window Manager
This build includes Desktop Window Manager, but it can crash at startup if no driver is installed, in which case software emulation is needed if no driver is available. LDDM drivers are now included by default, supporting many (but not all) GPUs of the time, however the DWM can run with a regular XPDM driver, using a registry edit.

There are two different ways of initializing DWM, one by modifying the registry, while the other being initializing a DLL via rundll32.exe. The more simpler rundll32.exe method is simply opening up the command prompt, and typing. This, however, randomizes the effects used with DWM. The other method of initializing DWM can be done via opening the Registry Editor, navigating to, creating a new key called DWM, then creating the following 3 DWORDs inside the key: Once making the following changes, simply log out of the system, then log back in.
