AdDuplex released its monthly usage share report for modern versions of Windows, and it shows that Windows 11 continues to grow, albeit at a relatively slow pace. Microsoft’s most recent operating system still ranks third, but it achieved 23.1% usage share among all versions of Windows 10 and 11. This is the first time it has surpassed the 20% usage share, after being stuck in the 19% range since the February report.
This still leaves it behind the two most recent versions of Windows 10 – version 21H2 and 21H1. Windows 10 version 21H2 is still the most widely used, and it actually grew a little more in June, reaching 38.2% market share, compared to 35% in April, when the previous report was published. This growth is offset by a decline in the use of Windows 1o version 21H2, which fell from 26.4% to 23.9% in the last two months, barely retaining the second place.
Older versions of Windows 10 also dropped significantly. The 20H2 version is down to 3.8% (6.1% in April), the 2004 version is at 5.2% (down from 6.5%), and older versions have seen residual declines. The percentage of Windows Insiders dropped slightly from 0.7% to 0.8%, potentially due to Windows 11 build 22H2 making its way to the Beta and Release Preview channels.
Looking at the history chart, you can definitely see that Windows 11 adoption has stagnated a bit compared to previous Windows updates since Windows 10 was introduced. Although it is still technically growing, it’s slower than most versions of Windows at this point in their lifecycle.
This is probably due to the system requirements for Windows 11, which are much higher than those required by Windows 10. Many Windows 10 devices cannot be upgraded to Windows 11 using the usual methods, which means that its Usage share will be limited until users purchase newer PCs with Windows 11.
As usual, this data is collected by apps using the AdDuplex v2 SDK, which is an advertising framework for apps on the Microsoft Store. This means that the sample size is relatively small, although the report does not disclose exactly how many devices were studied. The latest earlier reports had a sample of around 60,000 PCs, which is certainly a tiny fraction of all Windows PCs. Nevertheless, these trends give us an idea of the popularity of Windows versions.
