NetMarketShare's latest numbers are in, and Windows 10 is now on 19.14% of PCs. This is a big improvement from six months ago, when it was at just 11.85%.
Of course, not all usage numbers are created equal. According to StatCounter's numbers from May, Windows 10 recently passed Windows 7, coming in with 28.82% compared to Windows 7's 28.65%.
According to today's NetMarketShare numbers - which are from June - Windows 7 sits at 49.05%, which is a very far cry from Windows 10's usage.
Windows 10 has been steadily gaining adoption since it was introduced last July, but it will likely begin to slow. The offer for a free upgrade will end in just a few days; after that, users will have to pay at least $119 to upgrade to Windows 10.
As far as the rest of desktop operating systems go, Windows 8 and 8.1 still need to combine to defeat Windows XP, which isn't a surprise. Also, Windows Vista sits cozily alongside every version of OS X that's not El Capitan in the "Other" category.
While Windows 10 has a long road ahead before it catches up to 7, it most certainly will. Windows 10 is the last version of Windows, so its usage share can only go up.
