More than 10 per cent of global PCs are now running Windows 8, but Microsoft's new operating system still has a long way to go to catch up to its predecessor.
In December, Windows 8 market share hit 6.89 per cent while Windows 8.1 was at 3.6 per cent, or 10.49 per cent in total, according to data from Net Applications. That's up slightly from November, which put Windows 8 and 8.1 at 9.3 per cent of the market.
Between November and December, Windows 8 actually dropped slightly from 6.89 per cent to 6.66 per cent, while Windows 8.1, the newer version of the OS picked up steam, from 2.64 percent to 3.6 per cent.
At this point, however, Windows 7 still reigns supreme at 47.52 per cent of global OS market share, up slightly from 46.64 in November. Windows XP lands at number 2 with 28.98 per cent (down from 31.22 per cent) - four months before Microsoft plans to end support for the ageing OS.
Vista is clinging to life at number 4 with 3.61 per cent, but Windows 8 at least outpaces that unpopular OS. Apple's latest, OS X 10.9, has about 2.79 per cent of the market, up from 2.42 per cent the month before.
When it comes to mobile gadgets, meanwhile, iOS was the top operating system in December with 54.27 per cent, followed by Android at 35.41 per cent. Apple's share got a boost from the iPad, which made up 31.29 per cent of that traffic, followed by the iPhone at 22.36 per cent. Android 4.1 is the most popular version of Google's mobile OS at 13.29 per cent.
Net Applications found that Microsoft's mobile OS - Windows Phone - nabbed only 0.55 per cent of global mobile OS share in December, down slightly from the month before.
