Windows by the numbers: Windows 7's recalculated share shows faster-than-thought decline
Windows 7 dropped below the 50% user share mark last month, finally ceding the operating system majority on Windows PCs.
Ironically, the decline of Windows 7 was good news for Microsoft, which wants customers to move to the newer Windows 10 as soon as possible.
According to analytics vendor Net Applications, Windows 7's November global user share fell 3.5 percentage points, ending the month at 43.1%. November's plunge was the largest ever for the OS that debuted in 2009.
When only Windows personal computers were included in the calculation, Windows 7 ran 48.8% of all Windows machines, a month-over-month drop of 2.6 points. (The Windows-only percentage is larger because Windows powers 88.4% of the world's systems, not 100%; the remainder run macOS or a version of Linux.)
