Microsoft on Thursday afternoon revealed as part of its latest quarterly results that it has sold 180 million copies of Windows Vista in the roughly 18 months since the operating system’s launch in late January 2007. The news comes as Microsoft also reveals that it has earned more than $60 billion in revenue for one fiscal year and notes that its income grew 18 percent over the 12-month span. Unlike some past years, Microsoft credits the success to a broader success that includes Vista alongside the recently-launched Windows Server 2008, Office, various server apps, and the Xbox 360.
