Seattle PI | at | by Mike

Microsoft's Windows program became the top-selling operating system for running the server computers that anchor corporate networks and Web sites for the first time in 2005, according to market research company IDC.

Windows servers accounted for $17.7 billion in sales, passing the $17.5 billion garnered by the Unix operating system sold by companies including Sun Microsystems Inc. Unix has been No. 1 for more than a decade, IDC said Wednesday.

The worldwide server market rose 4.4 percent to $51.3 billion in 2005, its highest level in five years, IDC said. Demand for servers that use processors to run personal computers is fueling the growth of Windows and Linux operating systems.
