450 million copies of Windows 7 sold, consumer usage passes XP

In his Keynote opening the Build developers conference, President of Microsoft's Windows Division Steven Sinofsky touched on some updated facts on the still-relatively-young Windows 7 before diving into the demonstration of the next-generation Windows 8.

-Sales of Windows 7 is approaching 450 million copies.
-Windows 7 consumer usage is now greater than Windows XP.
-1,502 non-security product code changes have been delivered.
-Internet Explorer 9 is "the fastest-growing Windows 7 browser."
-542 million people using Windows Live services every month.

It's important to note that the second point is focused on consumers and not the enterprise, where XP is deeply entrenched.
