Windows 7 has finally become the dominant PC operating system, with more than half of all internet-connected computers using Microsoft's most recent OS, according to figures from StatCounter.
According to StatCounter, in June 2012 50.2 per cent of all computers used Windows 7, which was released in 2009. The next most popular operating system was Windows XP, which is still used by 29.9 per cent of users.
This is the first time that Windows 7 has gained more market share than the other operating systems put together.
But with Windows 8 just around the corner, Microsoft will undoubtedly be keen on getting all the XP users to switch to its latest operating system.
Windows XP was launched in 2001 and though hugely successful for the firm, Microsoft has struggled to wean users off the OS – especially after its successor Windows Vista proved a calamitous folly.
Microsoft is however set to end business support for XP within the next two years.
Meanwhile, not everyone agrees with StatCounter's measurements.
According to industry watcher NetMarketShare, Windows XP still accounts for 40 per cent of the operating system market, with Windows 7 marginally behind with 39 per cent.
NetMarketShare's figures do however show that Windows 7 continues to gain market share, up from 35 per cent in April, and mostly coming at the expense of Window XP's market share.
