Windows 7 has been declared the fastest selling operating system in history, selling an average of 7 copies every second for a total of 150 million (150,000,000) copies. Great job Microsoft! You know you have a great operating system when it sells in record numbers! Of course, what’s not to love about Windows 7? Anyone have anything they DON’T like about it?
