Windows 7 'most popular OS in 2011'

Research firm Gartner has revealed that by the end of this year Microsoft's Windows 7 will become the leading operating system worldwide in the PC installed base.

According to Gartner figures, Windows 7 will account for 42% of PC operating systems by the end of the year, with 94% of new PCs being shipped with Windows 7 in 2011.

Nearly 635 million new PCs are expected to be shipped globally with Windows 7 pre-installed in the systems.

Although corporates in the US and Asia Pacific are increasingly deploying the platform in enterprise markets, growth in Western Europe and Japan has slumped.

Economic uncertainties, political instability and the recent earthquake have lead to late and slow deployment for Windows 7 across these regions.

The figures also showed that Apple's Mac OS was on 4% of PCs in 2010 and is expected to grow to 4.5% by the end of 2011.

Apple's desktop OS is further expected to increase to 5.2% in another four years.
