The Redmond, Wash.-based software giant is throwing its muscle behind 64-bit software by beefing up versions of its Windows XP and Windows Server 2003 operating systems. Both will be designed to run natively on the AMD Opteron processor for servers and workstations, and the AMD Athlon 64 processor for desktops and notebooks.
Desktop and server beta releases are expected mid-year, according to a Microsoft announcement.
''Microsoft's 64-bit Windows operating systems represent an inflection point leading to higher performance and greater efficiency for businesses and consumers,'' says Brian Valentine, senior vice president of Microsoft's Windows division. ''We are pleased to usher in a new era of business value by extending our ongoing investment in 64-bit computing to the AMD platform.''
