Windows 7 is currently the world’s most popular desktop operating system, and statistics previously showed that more than 1 in 2 PCs were running it worldwide.

But preliminary figures for June provided to us by StatCounter show that, for the first time, Windows 7 dropped below 50 percent market share in North America, while Windows 8.1 adoption was on the rise.

In the first two weeks of June, Windows 7 declined to 46.83 percent, according to these early statistics, while Apple’s Mac OS X climbed on the second position with a share of 18.58 percent.

Windows 8.1 came second with 18.16 percent, followed by Windows XP, which obviously lost ground because it no longer receives updates and security patches since April 2014, to eventually reach 6.05 percent.

If you’re asking where Windows 8 is, it’s worth knowing that Microsoft’s core modern operating system dropped even more to a negative record of 2.84 percent, behind Windows Vista, which is still running on 2.95 percent of the desktop computers in North America.

Obviously, these figures can change by the end of the month, but the shift off Windows 7 could be a sign that Windows 10 has a chance to dethrone it and climb on the leading position in the desktop OS market, but it’s all a long-term shot, so it remains to be seen how things would evolve in the next few years.
