Windows 11 is getting close to reaching a double-digit market share according to AdDuplex’s survey for the month of November. The company’s latest data based on 60,000 Windows 10 and Windows 11 PCs shows that 8.6% of them are now running Windows 11, which is 3.8% points higher than last month.

Windows 10 version 21H2, the latest version of the OS that started rolling out on PCs that aren’t eligible for Windows 11 also showed up on AdDuplex’s radar this month. It has a 3.7% market share at the end of November, and it’s currently behind Windows 10 version 2004 (11%), Windows 10 version 20H2 (31.8%), and Windows 10 version 21H1 (36.8%).

If AdDuplex’s latest data shows that Windows 11 is on a steady rise, a separate analysis from the IT asset management firm Lansweeper (via Techradar) tells a different story. According to the study based on over 10M Windows PCs, only 0.21% of them are running Windows 11 in November. AdDuplex’s reports focus on a much smaller pool of PCs running AdDuplex ads, and it’s possible that Windows Insiders and early enthusiasts, the type of users more likely to be running consumer apps with AdDuplex ads, are biasing the results.

Microsoft announced last year that it had crossed 1 billion Windows 10 monthly active devices, and it’s probably too early for the company to share some official numbers for Windows 11. Starting with Windows 11 and Windows 10 version 21H2, feature updates for these operating systems will only be released once a year in the second half of the calendar year, and we may have to wait until Fall 2022 to get a better picture of the Windows ecosystem.
