Sun and Microsoft unveiled plans today to begin offering the Windows Server operating system on Sun's x86-based servers within 90 days.

While Microsoft may recommend installing the 'Server Core' version of Windows Server 2012, it may not be the right fit for you.

Sun Microsystems Inc. will start selling its lineup of 64-bit PC servers preinstalled with the Windows Server operating system from Microsoft Corp. within 90 days, the two companies said today.
