Since the release of Windows 11, Microsoft has been eager to see its market share increase rapidly. And according to the latest data given by research firm AdDuplex, Windows 11 is now installed on 19.3 percent of PCs (with another 0.3 percent running the Insider version), a figure that's up from 16.1 percent last month.

The current share of Windows systems

Windows 11 has gained a growing number of users since its official launch last October, and while the system still has quite a bit of polishing to do, many users whose devices meet the upgrade requirements are already looking at taking the next step on their PCs. In particular, Microsoft released the biggest Windows 11 update to date in February, which should also stimulate some users to upgrade. According to AdDuplex data, Windows 11 is already installed on almost 20% of computers, although the largest share is still Windows 10.

The share of Windows systems according to detailed versions is now

  • Windows 11 -- 19.6%
  • Windows 10 21H2 -- 21%
  • Windows 10 21H1 -- 27.5%
  • Windows 10 20H2 -- 17.9%
  • Windows 10 1903 -- 1.3%
  • Windows 10 1909 -- 2.5%
  • Windows 10 2004 -- 7.9%
  • Windows 10 1809 (and lower) -- 2.4%

Of course, AdDuple's data is not absolutely reliable, as it is based on data provided by only about 5,000 Microsoft Store applications using AdDuplex SDK v.2 or later. In any case, such surveys can reflect the trend of system change to some extent.

Windows 10 still has a higher market share

As you can see, the current share of Windows 10 21H1 is the highest, and the previous share of 21H2 brought by Microsoft has exceeded 20%. And as the most stable version of Windows 10 at present, 20H2 still has many users.

Microsoft is completing the launch of Windows 11 through all channels, such as downloading ISO images directly from its website and updating through Windows Update. New devices with Windows 11 pre-installed and features that should be promised (such as Android subsystems for Windows, etc.) should also increase their usage share. However, Windows 11, while surpassing the start of Windows 7, is still far from the market share of Windows 10 to begin with. It is also worth mentioning that Windows users are losing every year, with a current market share of 75%, compared to over 90% 10 years ago.
