==New features and changes==
===Setup===
The Setup now utilizes a brand new Slate themed background and user interface.
Upon launching the Setup, the user can now notice many drastic differences, as the previously used clock bitmap has been replaced with a countdown timer, and a Windows flag has been added to the title of each step. Simliarly, the "Final Countdown" step has been renamed to "Completing Setup".
Most Setup steps now contain a Help button, which can tell the user about what product keys do, which Upgrade option to choose, what computer names do and so on.
On the first page of Setup, Setup now mentions that the user is about to install a pre-release version of Longhorn and it will expire after 180 days.
A new "Clean install settings summary" page has been added, which enables the user to change the Installation location, Computer name, User account name, Regional settings, Keyboard layout and Time zone prior to installation. However, in this build and all subsequent builds, only the two first options are modifiable by the user.
The Drive partitioning stage of Setup now includes new options to refresh, delete, create and extend a partition.
A new Slate background that spells out the word "welcome" is now also present in the setup.exe autorun.
===Windows Explorer===
The Communication History prototype folder has been removed.
=== TCP/IP ===
A new TCP/IP stack has been introduced.
==Bugs and quirks ==
===Installation===
*Installing this build on a chipset from the Intel 440 series (which is commonly used by virtualizers) will result in an assertion failure in the AGP440.SYS driver, and thus result in a 0x0000007E (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) bugcheck when booting into the second stage of setup. This issue does not affect hardware outside of the previously mentioned chipset and can be bypassed by setting up kernel-mode debugging with WinDbg to ignore the failure[Guide Install Longhorn 4051 x64 chk], BetaArchive. 20 December 2012.. 
* When booting into the second stage of setup, the system will play a long beep on systems that have a PC speaker.
* As this build is a PDC build, it cannot be normally upgraded and thus can only be clean installed.
===TCP/IP===
The TCP/IP stack can be unstable at times.
===Branding===
As many branding changes did not make it into the Home Edition codebase at the time, the winver banner and Longhorn Screen Saver use the earlier Plex-themed branding.
