Windows Longhorn build 4051 is a Milestone 7 build of the Microsoft Windows "Longhorn" operating system and is also the build given to attendees of Microsoft's Professional Developers Conference 2003. It was leaked on 2003-10-20.
This Milestone 7 build was distributed at PDC 2003 in Los Angeles, California. This build, for its Professional version, has a x86 and a x64 version. The x64 version is not overly different from the x86 version, but it has a new setup style and several apps including Internet Explorer 6 have been optimized for x64 (often, the x86 ones do not run).
The Check/Debug version was previously not known to run; it will simply refuse to load setup due to a bugged processor check. However, BetaArchive user WindowsNeptune later found a fix to the x64 version.
Features[edit | edit source]
- The setup is updated to a Slate-style interface. Likewise, the login screen has been updated to have a black background and the "winver" banner has been updated. The Windows logo moves up on the login screen instead of down.
- New Documents and Photos and Videos libraries.
- The prefix "My" was dropped in most of the remaining folders, resulting in new names for locations Computer, Network Places and Contacts.
- Internet Explorer 6.05 included an add-on manager, a download manager, pop-up blocker, and a tool to quickly delete browsing history.
- Only the basic sidebar tiles are included: Classic Tray, Clock, Quick Launch, Slide Show and Sync.
- A new TCP/IP stack. IPv6 is also enabled by default in this new stack.
Do note that the x64 version of this build lacks the Sidebar.
Bugs and quirks[edit | edit source]
- This build cannot be upgraded from a previous build, and can only be clean installed.
- Notifications doesn't work for unknown reasons.
- The TCP/IP stack has a few bugs, however, most of them were fixed in build 4053.
