Windows 98 is maintaining its market dominance as the leader in operating systems worldwide and is used by roughly 35.12 per cent of computer users.
Business intelligence specialist RedSheriff said the prominence of Windows 98 is largely due to the fact it is prepacked with PCs and there are a number of improvements over Windows 95.
"These improved updates include a blurring in the distinction between the operating system and Web browser furthering Microsoft's monopolistic goals of eliminating Netscape which appears to be succeeding," the report said.
The second most used operating system with 20.95 per cent of the market is Windows 2000 followed by XP, which has 16.17 per cent of the market.
Further down the usage scale is the Mac operating system with a market infiltration of only 2.21 per cent.
The RedSheriff report said branding strategies such as featuring a Mac computer in the 'Sex and the City' television series has improved exposure and interest in the Mac, but it is still struggling to get a strong market foothold.
According to the intelligence data, the Microsoft Windows range of products make up 96.75 per cent of the global market.
