A few months later, AdDuplex released the Windows version usage report for July. The report was collected from 5,000 Microsoft Store applications running AdDuplex SDK v.2 or higher, and about 60,000 Windows PCs were sampled for the report. The highlight of this month is the debut of Windows 11, which was officially announced in June. As for Windows 10, the 21H1 version released in May is now running on more than 26% of Windows devices.
Just like the October 2020 update, the Windows 10 May 2021 update is an enablement package that lights up the new features that the operating system has prepared in the previous few updates. However, the underlying code base of 21H1 is the same as the 20H2 and 2004 versions, which means that these three latest versions are served with the same cumulative update. Therefore, it is not surprising to see that the latest version is launched faster than the previous version.
With Windows 10 21H1 now used on more than 26% of PCs, the three latest versions of the operating system account for nearly 88% of the usage share. The title of the most commonly used version of Windows 10 was retained by the 20H2 version, accounting for 36.3%, followed by the 2004 version, accounting for 24.6%. Windows Insiders running Windows 11 in the development channel account for nearly 1% of the total devices.
The Windows 10 21H2 version is also designated as an enablement package. However, as Windows 11 is expected to start rolling out later this year, it will be interesting to see how the usage share changes, as there are still questions about the speed of the new system launch and the hardware specifications that will eventually be supported.
