Historically, Microsoft developed its client and server operating systems on parallel tracks. Windows Vista shipped to manufacturing (RTM) in late 2006 as Build 6000. Windows Server 2008 followed over a year later, launching directly alongside Windows Vista Service Pack 1 (SP1). Both operating systems shared a unified code base starting with Build 6001.

: Rather than changing core file frameworks, Microsoft released KB4493471 . This critical architecture patch bumped the major build number up by one to 6003 and safely reset the minor revision counter to 20480 .
: The machine must already be fully updated to Windows Server 2008 SP2 (Build 6002) .
The official reason from Microsoft:
Specific editions supported this architecture. Legacy and Support Status
: While often unofficially referred to as "Service Pack 3" by enthusiasts because it changes the major build number, Microsoft officially maintains it as an update for Server 2008 SP2 . Inherited Features from Windows Server 2008
