AdDuplex: Windows 10 version 20H2 crossed 40% market share in April

Laurent Giret

Windows 10 version 20H2 is on its way to becoming the most popular version of the OS according to AdDuplex. 40.1% of the 70,000 PCs surveyed by the ad network were running Windows 10 version 20H2 in April, which represents a 10% points progression in a month.
The older Windows 10 version 2004 remains slightly ahead with a 40.6% market share in April, but the version 20H2 should easily become #1 next month when the upcoming version 21H1 should also be out. 11.1% of the surveyed PCs were still running the version 1909 of Windows 10 this month, and older releases all have a single-digit market share.

As always, keep in mind that AdDuplex’s data is based on PCs running the company’s ads, so it’s not a perfect picture of the Windows 10 ecosystem that now includes over 1 billion devices. Still, AdDuplex’s monthly surveys are better than nothing in the absence of monthly detailed stats from Microsoft.
