Some builds (such as Beta 1 and Beta 2) only display the build label in the version information dialog (Winver), and the icons are from Windows XP.When installing the milestone 2 builds, the OOBE (the setup process) is the same as Windows XP, but with different music.īuild 3683 (build date of September 23, 2002) was leaked on October 20, 2002, and was the first Longhorn build leaked to the Internet. The lab in which any given build originated is shown as part of the build label, and the date and time of the build follows that. At Microsoft, a number of 'Build labs' exist where the compilation of the entirety of Windows can be performed by a team. Typically, a team working on a certain feature or subsystem would generate their own working builds which developers would test with, and when the code was deemed stable, all the changes would be incorporated back into the main development tree at once. Higher build numbers didn't automatically mean that the latest features from every development team at Microsoft was included. A typical build label would look like 'Longhorn Build 3663.Lab06_N.020728-1728'. Most builds of Longhorn and Vista were identified by a label that was always displayed in the bottom-right corner of the desktop.
