240 million licenses and counting
It's been a year since Microsoft introduced Windows 7, which has gone on to become the fastest selling OS in history.
Redmond sold 240 million licenses in the first year of sales, not counting illegal copies and easily eclipsing its predecessor by selling a mind boggling 7.5 copies per second. Mind you, Vista was anything but popular and most punters viewed the 7 as a worthy successor to XP. Vista on the other hand was viewed as an inbred with special needs.
Windows 7 is currently installed on one in five PCs worldwide and it has a user satisfaction rate of 94 percent, which is 93 percent higher than Vista.
