Today, AdDuplex published its monthly report on Windows 10 usage. The data is based on the over 5,000 Microsoft Store apps that use the AdDuplex SDK v.2 or higher, and it was collected on August 27.
Compared to last month's report, the big news is that version 1909 is the most popular version now, finally passing 1903. The newest version, 2004, increased from 11.6% to 24.1%, as it's finally starting to roll out more broadly. Version 1909 decreased in usage from 36.8% to 35.5%, and version 1903 decreased the most, from 43.6% to 35.5%.
Obviously, the rest of the versions, even combined, make up a small piece of the billion-user pie. Version 1809 decreased from 3% to 2.4%, 1803 decreased from 2.5% to 2.1%, and version 1709 is stagnant at 0.8%. Older versions decreased from 1.2% to 1.1%, although that can likely be chalked up to a margin of error, and Insiders remain at 0.5%.
One key thing that you can see from the adoption graph is that adoption of version 2004 is really starting to pick up. It's still only available to seekers, meaning for those that go into Windows Update and manually choose to install it. The only people getting it automatically are those on a version nearing the end of support, meaning version 1809.
