Over 60 million Windows 8 licenses have been sold to date, according to Microsoft.
Microsoft this week announced record quarterly revenue of $21.45 billion for the three-month period ended December 31, 2012. Redmond's Windows Division posted revenue of $5.88 billion, up 24 percent from one year prior, though on a pro forma basis that number slides to 11 percent after factoring in net deferral of revenue for the Windows Upgrade Offer and the recognition of the previously deferred revenue from Windows 8 pre-sales.
All tallied, Microsoft figures it sold 60 million Windows 8 licenses to date, though it's unclear how many of those came from Surface sales versus Windows 8 desktop licenses.
"Our big, bold ambition to reimagine Windows as well as launch Surface and Windows Phone 8 has sparked growing enthusiasm with our customers and unprecedented opportunity and creativity with our partners and developers," said Steve Ballmer, chief executive officer at Microsoft. "With new Windows devices, including Surface Pro, and the new Office on the horizon, we’ll continue to drive excitement for the Windows ecosystem and deliver our software through devices and services people love and businesses need."
Microsoft's Entertainment and Devices Division, of which the Xbox 360 console is a part of, posted revenue of $3.77 billion, down 11 percent year-over-year. Nevertheless, the Xbox continues to be the top-selling console in the U.S., Microsoft says.
Despite the strong revenue numbers and Windows 8 sales, there's been a bit of turmoil behind the scenes . Internally, Microsoft is said to be blaming PC makers for not being ready with more attractive Windows 8-based touchscreen tablets. In response, Microsoft's hardware partners say that had they built up a stock of Windows 8 tablets, they'd be stuck with a bunch of devices that nobody wants.
