In just over a year since its release to manufacturer (RTM), Windows 7 has overtaken Windows Vista for the first time in total market share worldwide according to web analytics firm, StatCounter. Good news? I think so, after all Windows 7 is the best OS from Microsoft so far.

The firm’s research arm StatCounter Global Stats reports that, in August, Windows 7 took 19.4% total market share, compared to Vista’s 17.7% worldwide. XP continues to dominate the global market with 55.4%.

Microsoft already revealed that it sold in excess of 175 million copies of Windows 7. The company is projected to push over 300 million Windows 7 licenses by the end of 2010.

Windows 7 Vs Vista Vs Windows XP Market Share:

Vista continues to outperform Windows 7 in North America with a market share of 24.7% compared to 20.7% for Windows 7 (Windows XP 40.6%). In Europe the gap is even closer with 22.7% for Vista compared to 21.9% for Windows 7 (XP 47.5%).

The installed base of Windows Vista was very low in Africa, Asia and South America and now users in these regions are upgrading straight from Windows XP to Windows 7 giving rise to this leap in market share.

Aodhan Cullen, CEO, StatCounter commented, “Africa, Asia and South America are driving the increased market share for Windows 7. Although there has been extremely good growth for Windows 7 in Europe and North America, it has yet to overtake Vista in these regions.”

The data is based on an analysis of 15 billion page views for August 2010 collected from the StatCounter network of over three million websites.

Windows Vs Mac OS Vs Linux Market Share:

For the past year now, Windows, Mac OS X and Linux have been the number 1, 2 and 3 operating systems worldwide in terms of market share. This is no longer the case as Linux has lost the 3rd spot, leaving Apple platforms to occupy both the second and third positions on the OS market.

In order to more accurately describe usage share for Apple devices, the iPhone, iPod Touch and iPad are now being grouped under their common operating system ‘iOS’.

“Each of these devices can still be tracked separately using the Operating System Versions report. When these devices are combined, they have over 1% of global browsing share, which is now higher than Linux,” Net Applications reveals.

Statistics now indicate that while Windows continues to account for the largest number of users worldwide, with the Mac platform as runner up, customers running various Apple devices such as the iPhone and iPod, are in greater number than those running the Linux open source operating system.
