Every month, Statcounter publishes market share figures for the various Windows versions, but this month’s figures are something special. In September 2025, an ancient Windows version that hasn’t been updated in years saw a non-trivial bump in users. And yet, for some reason, Statcounter now shows that the global market share of Windows 7 rose sharply from 3.59 percent in August to 9.61 percent in September. During that same period, Windows 11 lost a negligible amount (from 49.08 to 48.94 percent) while Windows 10 lost a lot more (from 45.53 percent to 40.5 percent). It’s mainly due to Asia, where Windows 7 market share shot up from 5.64 percent in August to 18.67 percent in September!
