Windows Vista build 5112

Windows Vista build 5112 is the official Beta 1 build of Windows Vista, which was officially released on 27 July 2005. It is one of the first Beta 1-class builds to be compiled, and certainly, the first Vista build to become widely available.

At this point in development, Microsoft had decided that Windows Vista would be the final name of the operating system, hoping to boost the image and perception of the product among end users. Jim Allchin expressed their enthusiasm for the name, stating:

"'Vista' creates the right imagery for the new product capabilities and inspires the imagination with all the possibilities of what can be done with Windows – making people's passions come alive."

- Jim Allchin on the final operating system name

However, the name Longhorn was still used in numerous areas, such as within the About Windows dialog box, the registry entry for Winlogon, and on the boot screen. This is to be expected, considering the point at which this build was compiled (it was compiled two days before the announcement of the name change to Vista). The name Vista was only mentioned on the desktop watermark.

Setup
Although setup is mostly similar to the previous build, the hardware portion of setup now contains a dummy progress bar again. Build 5099 or later is required to upgrade to this build, but it is possible to upgrade from 5098 by replacing the sources folder (excluding ) from 5098 itself.

Aero
The Aero theme gained a slight update from build 5098, featuring more distinct borders and fixed text color on some windows. Using a patched uxss.exe file created by LucasB for the x86 compile or one by SeregaWin555 for the AMD64 compile, it is possible to initiate DWM with XPDM drivers. Otherwise, DWM could only be initialized with LDDM drivers, requiring the use of physical hardware with a LDDM-compatible graphics card (or a LDDM-compatible graphics card passed through to a VM using hypervisors such as QEMU). After replacing uxss.exe, navigate to, create a new key called DWM, then create the following 4 DWORDs inside the key: After making these changes, log out then log back on to initialize DWM. If DWM still doesn't start automatically, kill  process.

Windows Explorer

 * List Pane for Static Lists.
 * The ability to create a list from the New section in context menus has been removed.

Full Volume Encryption

 * Windows Full Volume Encryption API (fveapi.dll)
 * FVE Auto Convert Utility (fveauto.exe)
 * FVE Utility (fveconv.exe)
 * Windows Full Volume Encryption Tool (fvetool.exe)

32-bit EFI support
and  were added in the x86 compile for EFI booting. To use it, partition the hard drive as MBR, with a FAT32 C: partition for EFI boot, and a NTFS D: partition for Windows, both primary partitions, and install the build in BIOS mode to D: as normal. After that, switch to EFI mode, and execute  in an  EFI shell to create a boot entry in the EFI boot manager, then try to boot into it. If it fails, you may need to change the  identifier to point to your Windows install.

Miscellaneous

 * Two new icons have been added to the desktop, one leading to a supplemental driver installer that simply installs drivers made for Windows XP that aren't ready to work on this build yet, while the other is a document talking about Avalon and Indigo.
 * Media Foundation Protected Pipeline has been added.

Installation
Although this build can partition as intended during setup, the partitioning page doesn't refresh properly, requiring you to reboot your system in order to see the new partition.

DWM
On some configurations with patched, when   value is set to 0, the screen freezes (except for the cursor), until DWM is disabled, even if hardware acceleration is set to full. Along with that, if glass effects are enabled, there would be artifacts on non-Explorer window borders.
