Microsoft’s Windows 7 operating system has sold more than 350 million licenses in the past 18 months. That is very good news for Windows and for Microsoft.

We’ve done a lot in the last 18 months that improves upon the experience people have on their PCs with Windows 7. We launched Windows Live Wave 4 (which included Windows Live Essentials 2011 and enhancements to Hotmail), released the first service pack for Windows 7, and recently launched Internet Explorer 9. And we’re hard at work on further innovation for Windows. At CES this year we announced the next version of Windows will support System on a Chip (SoC) and last week at MIX11 we released the first platform preview to developers for Internet Explorer 10.
