Microsoft: 90 million copies of Windows 7 sold

It was just over a month ago that Microsoft officials said the company had sold 60 million copies of Windows 7. On March 2, they updated that tally, claiming 90 million copies of Windows 7 have been sold to date.

Microsoft released Windows 7 to manufacturing in July 2009 and kicked off consumer sales of the product in October of last year.

Microsoft Chief Financial Officer Peter Klein shared the new Windows sales figures during a March 2 presentation at the Morgan Stanley Technology Media & Telecom Conference.

Klein also confirmed that Microsoft will be launching the Office Tech Guarantee program before the end of this month. Last month, details leaked regarding Microsoft's plans to launch this Office upgrade program, which is designed to keep Office 2007 sales from falling off a cliff just before Microsoft releases the Office 2010 product. Original leaked details called for the program to kick off on March 5 and last through September 2010.

Here's a slide from Klein's Morgan Stanley presentation deck highlighting these points. (Click on image to enlarge.):

Microsoft officials said during last month's conference call that the current Windows 7 sales figures are primarily from retail/consumer purchases, and that enterprise purchases of the product have yet to commence in a major way.
