STATCOUNTER'S June 2026 report inaccurately claimed a significant drop in Windows' market share from 79% to 56%. This prompted speculation about the rise of Linux among observers. However, subsequent investigations revealed that these statistics were erroneous, leading to a correction with Windows' market share adjusted to 72%. Minor increases in competitors like Linux (4.39%) and macOS (16.37%) could not account for the reported drop in Windows.
The initial report's flaws were attributed to tracking errors that misclassified Windows users as unknown. StatCounter is expected to continue refining its data to avoid such inaccuracies in the future.
