AdDuplex released its monthly Windows 10 usage report today, which is based on data collected from apps that run AdDuplex SDK v.2 or higher on the date of August 22. This month's report focuses on the Windows 10 April 2018 Update, which was released a month ago.
The breakdown of Windows 10 usage is pretty much the same as it was last month. The Windows 10 April 2018 Update increased in usage from 84.2% to 86.7%, while the rest declined. The Fall Creators Update dropped from 10.3% to 7.8%, while the Creators Upddate dropped from 2.1% to 1.9%. The Anniversary Update dropped from 2.2% to 2.1%, and oddly enough, version 1511 - the only completely unsupported version of the OS - increased from 0.6% to 0.7%.
Version 1507 remained stagnant at 0.4%, while Insiders increased from 0.3% to 0.4%. You can expect to see a spike in Insiders soon, as Microsoft finalizes Windows 10 version 1809.
As you can see, the Windows 10 April 2018 Update started off at an unprecedented pace, but it's slowed down quite a bit. It should increase a bit more next month, before starting its decline when the next update comes out in October.
Finally, the Surface Pro 4 is still the most popular Surface by far, followed by two other Surface Pro models. The new Surface Go is already on the chart at 1.24%, beating out the Surface Studio, which comes in at a meager 0.12%.
