Keep the following in mind: “Windows 7” was previously “Vienna”, “Vienna” was previously “Blackcomb”.
As you know, Microsoft recently decided to make everyone feel stupid for assuming Windows Server “7” was ever anything BUT the codename for Windows Server 2008 R2. If that's true, then see the title to this blog entry. Up until Microsoft stated otherwise, the community’s assumption of the two being separate entities was perfectly pieced together through Microsoft’s minor/major release cycle in conjunction with a mash-up of official Windows Server presentations along the way. Being the net gopher that I am, I decided to dig up anything I could find in regards to Windows Server 2008 R2 being mentioned as a separate entity from Windows Server 7 in the same document, straight from Microsoft. Well, I finally struck gold. This discovery should make folks like MJ Foley, who felt the two were not *always* planned to be one in the same as was so confusingly-yet-authoritatively asserted by Microsoft, quite happy.
