AdDuplex has released its latest report, and it looks good for Windows 11. Per the firm, the new Microsoft operating system is running on 19.3% of all PCs that are part of their survey and data groups, up from 16.1% in January.

Though the number might seem good for Microsoft, it’s important to note that AdDuplex’s report doesn’t really cover all PCs worldwide. Instead, it looks at data from 5,000 Windows Store apps running AdDuplex SDK version 2.  At any rate, even with Windows 11 creeping close to 20%, Windows 10 version 21H1 is still the most popular Windows version.

In this month’s report, 21H1 is running on 27.5% of PCs, and Windows 10 21H2 is in a close second running on 21% of PCs. Those Windows 10 numbers are changed a bit over last month. In January, Windows 10 21H1 was at 28.6%, and Windows 10 21H2 was at 12.1%.

As far as official numbers from Microsoft, the company last said during its recent earnings call that Windows 10 and Windows 11 powers 1.4 billion monthly active devices. That number combines both versions of Windows, so it looks as though we’ll never be quite certain, offically at least, on how popular Windows 11 is. AdDuplex’s report, as well as Steam’s annual survey only, offer small peaks at the popularity of Windows.
