Earlier this week, Tami Reller, corporate vice president and chief financial officer for the Windows & Windows Live Division, spoke at the Bank of America Merrill Lynch U.S. Technology Conference. During her keynote, she talked about the excitement we continue to see for Windows 7 from consumers and businesses alike, as well as customer satisfaction for the OS.

In the first 6 months that Windows 7 has been on the market, we have sold over 100 million licenses. As we’ve said before, this makes Windows 7 the fastest selling operating system in history. To put it in a different way, in the first 6 months Windows 7 has been on the market, 7 copies of Windows 7 were sold every second. More than 12% of PCs worldwide are now running Windows 7 according to Net Applications and people are very happy with Windows 7. According to a survey Lifehacker did at the end of March, customer satisfaction for Windows 7 is at 94% which is fantastic. And both the excitement and satisfaction people have with Windows 7 is contributing to the strong growth in the PC market.

We’re also seeing that businesses are starting to get moving on their Windows 7 deployment plans which has resulted in a 14% increase in sales for business PCs. According to Forrester, Windows 7 will become the new standard for most commercial (business) PCs within 12 months.
