The launch of Windows 7 propelled Microsoft to record third-quarter revenue of $14.5 billion, a 6-per cent increase from a year ago, the world's largest software company said on Thursday.
Microsoft earned $4 billion in net income, a rise of 35 per cent compared to the same quarter a year ago.
"Windows 7 continues to be a growth engine, but we also saw strong growth in other areas like Bing search, Xbox LIVE and our emerging cloud services," chief financial officer Peter Klein said. "Our record third-quarter revenue along with continued rigor on cost management resulted in exceptional earnings-per-share growth."
Windows revenue was up 28 per cent, compared with the same quarter a year earlier, driven by strong demand for Windows 7. Microsoft said that more than 10 per cent of all PCs worldwide are now running Windows 7, making Windows 7 by far the fastest-selling operating system in history.
