Despite disappointing consumers and being snubbed by businesses, Windows Vista's numbers keep growing, with Microsoft claiming it has now shipped 88 million copies of the operating system, almost double the number of copies of XP in the same amount of time at its launch.
In late July, Microsoft said it had hit the 60 million shipment mark mark with Vista.
Microsoft had previously said that it had shipped 20 million copies of Vista in its first month and 40 million copies of Vista in the first 100 days.
Microsoft credited Vista with helping it beat Wall Street expectations and raise financial projections for the rest of the year. The company last week reported revenue up 27% from the same quarter in 2006.
The 88 million figure mostly includes Vista-installed PCs bought by consumers and small businesses, as well as packaged copies of Vista sold in stores or online.
It does exclude the tens of millions of Windows corporate volume licences. There, many enterprises continue to hold off on deploying Vista, acknowledged CFO Chris Liddell, though he expects them to start deploying it when Vista Service Pack 1 (Vista SP1) arrives in the first quarter of next year.
