Numerous tech publications are reporting on a chart from Statcounter Global Stats that shows a decline in Windows 10 usage and an increase in Windows 11 usage as of June 30, 2025. Some articles claim that Windows 11 has caught up to Windows 10 in market share, but the difference is so small it may fall within statistical error. Statcounter's data reflects pageviews rather than actual market share, which can misrepresent the popularity of the operating systems. The firm, established in 1999, has seen a decline in its customer base from 3 million in 2009 to 1.5 million by 2022. Statcounter's data comes from small to medium-sized websites and does not include major sites like Google and Facebook, leading to potential inaccuracies in interpreting market share. Trends indicate a gradual decline in traffic from Windows 10 devices and a rise from Windows 11 devices, particularly as Windows 10's end-of-support date approaches, but these trends do not necessarily reflect the overall Windows PC population.
