I'm gonna update the Welcome Screen since this is not what 5048's logon looks like. Over the weekend, Twitter user (who makes a habit of digging deep into old development versions of Windows) gave us a look at the earliest known version of Aero in a Longhorn development build from March of 2003, nearly four years before Vista would be released to the public. Windows Vista build 3790.1232 is one of the first builds of Windows Vista compiled after the development reset, and the first to be built by the new winmain build lab.It is essentially a recompile of a contemporary Windows Server 2003 Service Pack 1 build with the same number, and therefore not functionally a Longhorn build. It was in this build that Microsoft took out the sidebar for awhile. One of Vista's most noticeable and memorable additions was the 'Aero' design, which used Direct3D to draw translucent, glassy windows that could fade gracefully in and out of view, replacing the 2D windows from older Windows versions. Microsofts insider Paul Thurrott has posted new screen shots of Longhorn build 5048. So Id say for removing timebombs/activating some of these post-reset builds you should either: -Use a version of TweakNT corresponding with your build (there are versions that work with 52) - Use the Vista Developer Activator I mentioned presumably for pre-Beta 2 builds or later. Longhorn was supposed to include a filesystem to replace NTFS, something we still haven't gotten almost two decades later. Here is my video tutorial on how to install Windows Longhorn Build 3683 in VirtualboxCheck out VIKKNETTIC here. Microsoft planned a huge list of new features for Longhorn (and its planned successor, codenamed Blackcomb), many of which never saw the light of day.

If you're interested in the history of Windows, you probably know a bit about ' Longhorn,' Microsoft's internal codename for the OS update that would eventually become Windows Vista.
