Fun with Version Numbers

IMG00005-20081103-2233When I talk Windows junk, specifically with fellow IT guys I do expect them to know a little history. And I don’t mean when data was stored on punch cards or tape although I with I could have been there for that.

I mean Windows basics…like version numbers. It’s very frustrating when you call yourself a Windows guru but you don’t know that Windows 2000/XP/Vista is NT. Totally don’t expect end users to know…don’t get me wrong, but when someone who bills themselves as a Windows Admin gets this wrong I just have to say something.

Yes…I’ve had conversations where I have to actually explain to people that Windows 2000 was NT…they just thought it was just a different operating system. Now granted Microsoft made a rather good change in some of its core architecture from NT4, but when it comes down to it…it is good ol’NT. So to help educate people, I’ve made a list.

  • NT4 = well…NT4
  • Windows 2000 = NT 5.0
  • Windows XP = NT 5.1
  • Windows Server 2003 = NT 5.2
  • Windows Vista = NT 6.0
  • Windows Server 2008 = NT 6.0
    Earlier this year, Microsoft synced the Windows codebase of Vista SP1 and Windows Server 2008 so they are the same. This is not to say the functionality is the same, they are drastically different but the underlying code is the same. Just another tidbit I thought I'd share.
