Microsoft has released numbers that show the software maker selling seven copies of its Windows 7 operating system per second.

"Windows 7 is the fastest selling operating system in history," said Brandon LeBlanc, Microsoft's in-house Windows blogger, in a post Wednesday. All told, Microsoft has sold more than 150 million Windows 7 licenses since the product debuted last October.

LeBlanc added that 75% of enterprises are either actively deploying or evaluating Windows 7. "That's amazing," said LeBlanc.
