I downloaded the data from StatCounter, and we found that an operating system labeled “Unknown” suddenly accounted for 21.45% of the desktop market. This category could include any device where the browser’s user agent is modified, unavailable, or cannot be correctly identified by StatCounter.
That means a portion of those “Unknown” devices could very well be Windows PCs. The more likely explanation is that StatCounter misclassified a large number of devices rather than Windows suddenly falling below 60% or contributing to Linux’s growth.
It’s not the first time StatCounter has reported wild numbers. In 2025, a number of outlets and influencers reported that
Windows 7 was gaining market share to prove a point that Windows 11 is a terrible operating system.
