Windows 7's marketshare rose by 3.22 percentage points last month, while Windows 8 fell 0.67 percent and the Windows 8.1 update gained just 0.24 percent. The gains of Windows 7 primarily originate from Windows XP, which fell 2.62 percentage points to 11.98 percent.
With less than a month to go before the arrival of the free Windows 10 upgrade it's going to be very interesting to see if Microsoft will succeed in converting most Windows 7 and Windows 8.x users to its newest platform.
In fact, Windows 7 saw the most growth of any operating system version in June: up 3.22 percentage points to hit 60.98 percent. Windows 8 meanwhile fell 0.67 percentage points to 2.90 percent while Windows 8.1 gained just 0.24 percentage points to hit 13.12 percent. Together, they owned 16.02 percent of the market at the end of June, down from 16.45 percent at the end of May. Windows 8 and Windows 8.1 have yet to pass the 20 percent market share mark, and with Windows 10 debuting on July 29, they may never pull it off.
