Windows Vista will not be the last major release of an operating system from the Redmond Company. The statement belongs to Microsoft Chief Executive Officer Steve Ballmer. Following the Windows Vista launch event at the Manhattan's Cipriani restaurant, Steve Ballmer fended off speculations that Vista is the last client OS.

On the day he kicked off the launch of Windows Vista, Ballmer stated that "there's plenty more where that came from." However, the Microsoft CEO failed to provide additional details about the company's plans for future releases of Windows operating systems.

"We've got a very long list of stuff our engineers want to do, a long list of stuff all of the companies here want us to do. All these things will evolve, and the operating system will need to evolve with them," commented Ballmer.

Microsoft remains loyal to its vision that connects the desktop with the Internet based services. In this context, the Redmond Company will bundle the two dimensions with its future strategy.

"With every new release of Windows, I suspect I'll be able to tell you about how much more innovation there is to come from all of us in the industry. The fact that you can get upgrades helps create momentum. The truth is, there are a variety of needs in the home. Some people work from home, some don't, some people have a high-end consumptive use-style, some people are looking for things that are much lower-end, and we were trying to meet that range," Ballmer added.

There is little information available about Microsoft's upcoming operating system, codenamed Windows Vienna, and Ballmer even dodged the questions related to Windows Vista Service Pack 1 that is scheduled for availability in the second half of 2007.
