Windows 10's latest update is outpacing Windows 11 adoption right now

pcgamer.com:

Windows 11 began its rollout to compatible Windows 10 PCs back in October 2021, and it appears that just under 20% of PCs have made the leap to the new OS. 

That's coming from monthly data procured by ad network AdDuplex, which samples 60,000 PCs running software using its ad tech across various apps. That's not the largest sample size ever, but is certainly a good indication of where we're at in terms of OS adaption. The ad network found that while Windows 11 has hit a decent milestone for its release, there's still a long road ahead for Microsoft's latest OS.

With the release of Windows 11, Microsoft effectively forked its users off to either Windows 11 or the Windows 10 21H2 update. The Windows 10 21H2 update arrived in July, and in October the Windows 11 update was offered to users with compatible PCs. Right now, it's the Windows 10 21H2 update that's gained the lion's share of updating users, at 21%. However, Windows 11 adoption isn't too far behind, sitting at 19.3%, according to the data.

Windows 11 is sure to outgrow Windows 10 eventually, but as XDA Developers note the number of Windows 11 users has only grown a small percentage in the past month. In January, Windows 11 usage share was 16.1%, making for a 3.2% increase in users for February. 

Meanwhile, the Windows 10 21H2 update was on just 12.1% of users in January, which rose to 21% in February. 

Windows 11 Insiders make up another 0.3% share, though the many active versions of Windows 10 make up the largest slice of the pie: Windows 10 21H1 still holds 27.5% share, and the Windows 10 20H2 update from 2020 holds another 17.9%.

There are even a few users still rocking Windows 10 update's from 2018 or older, at 2.4%.
