Microsoft has announced that it has sold more than 240 million copies of Windows 7 (which was launched a year ago this week), Those numbers make it both Microsoft’s and the industry’s fastest-selling OS. The company needed it too. Windows 7 has helped the company overcome much of the negative consumer opinion after the launch of its Vista OS.
It should be noted that Apple has sold about 13.8 million Mac machines worldwide, but still isn’t large enough to compete in sheer new OS installs. It has however received a much faster adoption of its latest OS version.
