Microsoft Windows 7 Sales Hit 150 Million

Microsoft has announced that it has sold 150 million licences for its Windows 7 operating system.

The company calculates that seven copies of Windows 7 are being sold every second, making it the fastest selling operating system in history.

The company launched the OS in October last year, along with Windows Server 2008 R2.

The software giant believes that Windows 7 sales have been fuelled by intense demand in the enterprise sector, with over 75 per cent of organisations looking to deploy Windows 7 on their systems.

Other observers put the credit for Windows 7's success on its ability to work seamlessly with Windows Live.

Microsoft this week announced the availability of a beta version of its new Windows Live Essentials suite, updating the Messenger, Photo Gallery, Movie Maker and Sync software.

Writing on the Windows blog, Microsoft spokesperson Brandon LeBlanc wrote: “Together, the new Windows Live Essentials combine the power of the PC and the reach of the cloud to enhance the Windows 7 experience.”
