Microsoft has finally crossed an important milestone for Windows 11, months ahead of Windows 10’s end of support cutoff date. Stat Counter, spotted by Windows Central, now lists Windows 11 as the most used desktop operating system nearly four years after its release, with 52 percent of the market, compared to 44.59 percent for Windows 10.

Windows 11 became the most popular OS for PC gaming in September, but overall adoption had still been lagging behind Windows 10 until now. Leaked data in October 2023 also revealed Windows 11 was used by more than 400 million devices at the time, a slower adoption pace than Windows 10 — which took just a year to reach 400 million devices compared to Windows 11’s two year period.

Part of the slow adoption is down to Windows 11’s hardware requirements. While Microsoft offered a free upgrade to Windows 10 users, millions of machines have been left behind due to stricter CPU and security requirements. Microsoft has been trying to convince the owners of these machines to upgrade their hardware in order to get Windows 11, sometimes with a full-screen prompt.

Windows 10 is due to reach end of support on October 14th, and Microsoft recently revealed it would give away a free year of extra security updates to consumers if they were willing to enable Windows Backup and sync their Documents folder to OneDrive. If you don’t want to do this, you’ll have to pay $30 for a year of updates, or redeem 1,000 Microsoft Reward points.
