Windows 2008 SP1
For those of you who have played with the Windows Server 2008 RTM you may be left wondering why the version is shows as “Build 6001: Service Pack 1”. Hang on, Servcie pack 1? But it hasn’t even shipped yet!
Iain McDonald explains why over on his blog. Vista and Windows 2008 are have an almost identical codebase, so by making windows 2008 service pack 1 on launch they’ll be able to deploy updates for both operating systems . I’d suggest you read his post though, as it’s an interesting read!
