Microsoft's Windows operating system increased its online market share in February.
According to web analytics firm Net Applications, Microsoft grew its operating system share to 88.42%, from 88.2% in January.
Apple on the other hand lost 0.28%, and now holds 9.61% of the market. Linux went up slightly to 0.88%.
Microsoft's Windows XP is well ahead of Windows Vista in the market, holding 63.67%. Vista has 22.79%. In February, XP fell marginally and Vista was up slightly - in both cases the movements were well below 0.5%.
XP's continuing dominance illustrates the problems Microsoft is going to have persuading users to jump to the forthcoming Windows 7 OS, which is said to be very similar to the much aligned Vista.
