After several delays, the long-awaited update to the Windows client OS, Windows Vista, is expected to be on its way to manufacturers Wednesday.The IDG News Service reported several weeks ago that Vista\u2019s release to manufacturers (RTM) had been pushed from Oct. 25 to Nov. 8 because a last-minute bug in one of the last builds of Vista had to be repaired. Microsoft\u00a0called a conference call about Vista with Jim Allchin, co-president of Microsoft\u2019s platforms\u00a0and services division, for 2 p.m. EST. It was considered likely that\u00a0Vista\u2019s RTM would be the subject of the call.Once Vista is in the hands of manufacturers, hardware vendors can begin installing it and configuring it on computers that will be sold via retail channels beginning in January 2007, according to Microsoft\u2019s current schedule.Microsoft also plans to have Vista in the hands of business customers by the end of November, and is hosting a launch event in New York on Nov. 30 to mark that occasion. The company also will launch Office 2007 and Exchange Server 2007 at that event.Vista has been a long time in the making, and was originally scheduled to hit retail channels this month in time for the busy holiday shopping season. Microsoft is offering coupons through its hardware channel to encourage customers to buy Vista-ready PCs during that time so they can upgrade to Vista when it\u2019s available generally. Business customers have said they likely will not upgrade to Vista immediately after its release, but will probably wait until a first service pack for Vista is available.-Elizabeth Montalbano, IDG News Service (New York Bureau)Related Links:\n\nMicrosoft: Office 2007 Ready for Action\n\nMicrosoft Confirms Nov. 30 Vista Release to Enterprises\n\nMicrosoft Vista to Get VoIP\n\nSimultaneous Launch of Vista and Office 2007 PlannedThis article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
