Nearly three and a half years after its release, Windows 10 last month surpassed its enterprise predecessor, Windows 7, as the most popular operating system on the planet.
According to analytics vendor Net Applications, Windows 10 jumped by 1.1 percentage points in user share in December, climbing to 39.2% of all personal computers and 45.5% of all PCs running Windows. (The second number is larger than the first because Windows does not power all PCs; in December, Windows ran 86% of the world’s systems. Most of the remainder ran macOS, Linux or Chrome OS, in decreasing order.)
Meanwhile, Windows 7 lost 2 percentage points last month, four times the loss of November and the largest one-month decline in over a year. Windows 7 ended 2018 on 36.9% of all personal computers and on 42.8% of all Windows PCs.
