Yes, Windows Server 2008 R2 is 64-bit Only

I got asked a question yesterday at work regarding the architecture of Windows Server 2008 R2.

Just for the record and to ensure anyone else to who may be interested knows, Windows Server 2008 R2 is available in two architectures:

  • 64-bit (x64)
  • Intel Itanium (ia64)

There is no 32-bit (x86) version of Windows Server 2008 R2, nor will there be 32-bit versions of any future Windows Server operating systems.

This move to a pure 64-bit architecture is also following suit in the server technologies and products including Exchange, SharePoint, SQL Server and more to come no doubt.

I would also anticipate that Windows 7 is the last client operating system to be available in 32-bit and I think that Windows 8 or however it manifests itself will also likely be a 64-bit only architecture operating system.

I don’t know what architect Microsoft Midori will be based on but that’s a totally different subject and one I don’t know anything about yet to comment on.
