Windows 8 has returned to a steady growth rate after leaping the previous month, according to one stats company.
After a big leap from 5.4% global market share in July to 7.4% in August, Net Applications' data showed Windows 8 climbed to 8% in September.
The slowing growth rate is almost certainly down to office workers - who tend to use older operating systems - returning to work after the summer holidays.
Net Applications showed Windows 7 also gaining almost a full percentage point, while XP and Vista continue to steadily decline.
Overall Windows holds 90.8% market share on desktops and laptops globally.
Those stats are backed up by rival analytics' firm StatCounter, which showed Windows 8 had a 7.5% market share globally, but that includes PC OSes as well as mobiles.
