PCWorld: In a blog post, Microsoft's Dan Reger announced, "Windows Server 2008 R2 will be the last version of Windows Server to support the Intel Itanium architecture. SQL Server 2008 R2 and Visual Studio 2010 are also the last versions to support Itanium."
That's bad news for Intel, which makes the processor. Earlier, Red Hat also announced that it would drop Itanium support in the latest version of its enterprise server software.
However, most Itanium servers run HP's version of Unix, HP-UX, and HP has committed to supporting the processor in the future.
