AdDuplex has published an updated report with Windows’ desktop share. Windows 11 highest adoption (up more than 3 percentage points since April) is the peak, although Windows 10 is still in first place.
Windows monopolizes the PC operating system segment with an estimated 88% share, while Apple’s macOS has a quota close to 10% (Mac’s share of computers sold) and Linux retains the rest, 2%, far from its free, open source and potential benefits . The situation is not expected to change in the medium term unless Apple licenses macOS to third parties and Linux cannot be installed as a pre-installed system on new OEM computers.
Windows quota
AdDuplex only calculates the acceptance of different versions of Windows and most certainly your data is not the most reliable, because it only calculates them from the collection of Microsoft Store apps that use its SDK. In any case, it helps us estimate the trend.
And this tells us that Windows 11 is still improving, but more slowly than expected. The reasons are known and start with the increase in hardware requirements for migration to it. In addition, the system does not inspire, it is a tweaked Windows 10 that lacks development and features that were promised at the time and have not yet been activated. On the other hand, the greater stability of Windows 10 and its official support until 2025 advise many users not to move it.

Anyway, the sale of new equipment (all with Windows 11 already pre-installed) and the improvements that gradually come with each update ensure that its share will continue to rise, like 3 points from April to here. You can see the rest in the chart with the last two versions of Windows 10 above:
- Windows 10 21H2: 38.2% (+3.2 points)
- Windows 10 21H1: 23.9% (-2.5 points)
- Windows 11 21H2: 23.1% (+3.4 points)
- Windows 10 2004: 5.2% (-1.3 points)
- Windows 10 20H2: 3.8% (-2.4 points)
- Other versions of Windows 3% (-0.4 points)
- Windows 11 Insiders: 0.8% (+0.1 points)
In total. Windows 11 continues to grow, but slower than expected. Windows 10 is still king, although that may change in the coming months.
