In November 2021, AdDuplex compiled data based on 60,000 Windows 10 and Windows 11 computers, and released the survey report on December 1. According to this report, Windows 11 users are more than doubled in November -- 8.6% of computers are now running Windows 11, compared to just 5% in October.

Windows 10 version 21H2, the new version for PCs that don't qualify for Windows 11, also appeared in AdDuplex's report this month.  With a market share of 3.7 percent at the end of November, it currently ranks behind Windows 10 version 2004 (11%), Windows 10 version 20H2 (31.8%) and Windows 10 version 21H1 (36.8%).

Microsoft will accelerate the promotion of Windows 11

Previously, Microsoft has stated several times that they will accelerate the promotion of Windows 11, which is due to the relatively positive feedback from users who have upgraded to Windows 11. At the same time, Microsoft also admitted that the current Windows 11 is still being plagued by various bugs. For example, recently some devices using specific versions of the Intel SST audio controller driver have experienced upgrade hurdles, resulting in blue screen errors on the computer, while the inconvenient right-click menu and the laggy UI are also a major concern for users to be fixed.

Therefore, although Windows 11 is known as an upgrade with a lot of design improvements, there are still many users who are on the fence about whether to upgrade, and Microsoft has promised to continue supporting Windows 10 in the coming years.

If the latest data from AdDuplex shows that Windows 11 is on a steady rise, a separate analysis by IT asset management firm Lansweeper says differently. According to the study, which is based on more than 10 million Windows PCs, only 0.21% of PCs were running Windows 11 in November. AdDuplex's report focuses on a much smaller niche of PCs running AdDuplex ads, and potentially Windows Insiders and early enthusiasts, which are more likely to be users running apps with AdDuplex ads on consumer applications, thus skewing the results.

Microsoft announced last year that it had achieved landing 1 billion monthly active Windows 10 devices, and it may be too early for Microsoft to share some official numbers for Windows 11. Starting with Windows 11 and version 21H2 of Windows 10, feature updates for these operating systems are only 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 idea of what's going on in the Windows ecosystem.
