Unmentioned by Microsoft in all the hubbub around XP and Windows 7 is Vista, the hapless operating system that debuted in early 2007.
According to Net Applications, Vista accounted for just 8.9 percent of all operating systems last month, down a percentage point in the last three months and off 4.5 points in the last year.
Vista never cracked the 20 percent mark by Net Applications' measurements, peaking at 19.1 percent in October 2009, the same month Windows 7 launched.
Net Applications calculates operating system usage share with data obtained from more than 160 million unique visitors who browse 40,000 websites that the company monitors for clients. More operating system stats can be found on the company's site.
Windows XPs market shared has dropped 4.4 percentage points in the last two months.
