NEW YORK - Microsoft Corp. launched Windows Vista for businesses on Thursday, unveiling the first major upgrade of its dominant operating system in five years and predicting that over 200 million people will run new Windows, Office or PC server software by the end of 2007.
Vista upgrades the operating system used on more than 90 percent of the world's computers and features translucent windows to make it easier to view items on the desktop, an improved search system, and improved reliability and security.
The world's largest software maker will not make Vista widely available for retail customers until January 30, giving computer manufacturers time to load the operating system onto new PCs.
Plagued by a series of development delays, Windows Vista is the cornerstone of a new product cycle at Microsoft and a crucial litmus test for the company's ability to maintain its grip on desktop computer customers.
