Windows 10 is now the second most popular desktop operating system, based on data from Net Applications' Netmarketshare service.
Windows 7 remains the top dog with 52.37 percent of the market, down a minuscule 0.13 percent, as Windows 10 rose to second with 12.82 percent (up 0.97 percent), Windows 8 fell to 2.43 percent (-0.25 percent) and Windows 8.1 fell to 9.83 percent (-0.57 percent).
Windows 10 uptake has grown, but it may be a cause of frustration at Microsoft that Windows 7 remains so far ahead in the operating system stakes, particularly as Windows 10 has been offered as a free upgrade for six months or so.
The company will no doubt hope that the rollout of new devices like the Surface Book and other laptops from its partners will continue the rise of Windows 10.
The new operating system may also get a boost from enterprise deployments, as many firms are likely to be holding off from an upgrade of Windows 7 estates while they test Windows 10 and sweat any Windows 7 assets that can't be upgraded.
However, it is worth noting that Windows 10 is now seen as one operating system, so this figure includes every tablet, ultraportable, Internet of Things device and so on that runs Windows 10. This slightly skews the operating system against other figures in the list.
Old stalwart Windows XP is now in fourth place, without really losing much ground. The operating system stands at 11.24 percent (-0.18 percent), despite the end of security support for the platform almost two years ago.
Away from Windows, the figures show a nominal rise in Linux use to 1.78 percent (+0.07 percent) and Mac OS X claims 3.72 percent (+0.28) for 10.11 El Capitan and a slight drop for 10.10 at 2.2 percent (-0.13).
