NEW YORK -- Microsoft has released to consumers the Windows Vista operating system and Microsoft Office 2007.

The two products will be available in more than 70 countries, in 19 languages (with 99 languages anticipated by the end of the year), and at more than 39,000 retail stores and online.

The launch marks the achievement of a collaboration between Microsoft and its customers and partners.

"Windows Vista and Microsoft Office 2007 will transform the way people work and play," said Bill Gates, chairman of Microsoft. "Personal computers have become a key part of the daily lives of almost a billion people worldwide. Millions of consumers had a hand in helping us design, test and create the most exciting versions of Windows and Office we've ever released. Windows Vista and Microsoft Office 2007 squarely address the needs and aspirations of people around the globe."

The consumer launch of Windows Vista is also expected to unleash a flood of new next-generation hardware, software and entertainment devices and services. Currently, more than 1.5 million devices and peripherals are on the market that work with Windows Vista, including more than 2,500 that are certified for Windows Vista.

In addition, thousands of PC manufacturers and system builders around the globe will deliver the Windows Vista operating system and Microsoft Office 2007 on new PCs.

Microsoft has mobilized employees -- including executives, engineers, developers and product managers -- to spend the launch day assisting salespeople at retail stores across the United States.
