The next Windows operating system, named Vienna, was confirmed by Microsoft. It will take about two-and-a-half years time to deliver the successor of Vista, and hopefully Microsoft will release it before the end of 2009.

At the RSA Conference in San Francisco, Ben Fathi, corporate vice president of development with Microsoft's Windows Core Operating System Division said, "We put Longhorn on the back burner for awhile, then when we came back to it, we realized that there were incremental things that we wanted to do, and significant improvements that we wanted to make in Vista that we couldn't deliver in one release." He also said the release will have some cool new features.
