As is the case every month, AdDuplex has released its Windows 10 version usage report for the month of April. The report is collected from 5,000 Microsoft Store apps that are running the AdDuplex SDK v.2 or higher, and the sample size is around 70,000 users. The highlight this month is that the Windows 10 October 2020 Update (version 20H2) has gained 10% share since March to now account for 40.1% of the total number of PCs running Windows 10.
The bump this month makes version 20H2 the second most popular version by a small margin (0.5%). The May 2020 Update – version 2004 – remains the most popular version of Windows 10 at 40.6%. However, the percentage share dropped for the first time, coming from 42.1% last month. Cumulatively, the two most recent versions of Windows 10 account for 80.7% of all devices running the OS.
The November 2019 Update (version 1909) that is slated to reach the end of service next month dropped by 7.3% to account for 11.1% of all devices. Other older versions such as the May 2019 Update (version 1903) which is no longer supported dropped from 4.6% last month to 3.3% in April. Version 1809, 1803, and older dropped slightly as well. The share of devices running Insider builds further increased this month to 0.7%, up from 0.5% last month.
Most Windows 10 users are now running the two latest versions of the OS that are serviced by the same cumulative updates. With version 1909 reaching the end of support next month and the next major update – version 21H1 – containing the same bits as that of versions 2004 and 20H2, all three supported versions will for the first time be serviced by the same patches. Since 21H1 is an enablement package that lights up minor new features, it will be interesting to see if it will be rolled out at the same pace as that of 20H2 or if the Redmond firm adopts a faster release pace for the update.
