Advertising platform AdDuplex has released its latest report on the market share of different versions of Windows 10. The data in the report is gathered from 5,000 Microsoft Store apps that use the company"s AdDuplex SDK v.2 or higher, and it was collected over the course of the day on February 24.
After the reports took a bit of a hiatus last year, AdDuplex is back on its monthly schedule, so we can compare the growth directly to last month"s report. The Windows 10 November 2019 Update is now on 22.6% of Windows 10 devices, a nearly 50% growth from last month"s 15.2%. As Windows 10 version 1809 nears the end of support, more machines are being automatically updated to the latest version of Windows 10, supporting this growth.
This also explains why most of the growth has come at the expense of version 1809, which dropped from 22% usage to 16.4%. Meanwhile, version 1903 - also known as the May 2019 Update - has only gone down slightly, from 53.4% to 52.6%. Older updates already have a pretty low install base, and changes are minor: the April 2018 Update is down from 5.6% to 2.9%, and the Fall Creators Update dropped from 1.3% to 1.2%.
We also get to take a look at the pace at which the latest update is rolling out to users, and it"s clear that it"s a little slower, even compared to the May 2019 Update. Unless your current Windows 10 version is nearing the end of support, you won"t get updates automatically, which explains the slower growth.
This time around, AdDuplex hasn"t included information about usage of Surface devices, though it"s unlikely the scenario has changed dramatically since last month.
