It’s been almost a month since Microsoft officially released Windows 11, and the new OS is already running on over 5% of PCs surveyed by AdDuplex in October. More precisely, 4.8% of the 60,000 surveyed PCs by the company were running the production version of Windows 11, with 0.3% of users also running Windows 11 Insider builds.

This latest survey also shows that Windows 10 version 21H1 is now the most popular version of Windows 10 with a 37.6% market share, and it’s followed by the version 20H2 at 34%. As usual, this relatively small sample isn’t a perfectly accurate picture of the Windows ecosystem, which now includes over 1 billion devices.

It’s still early days for Windows 11, which is now being offered as an optional free upgrade on eligible PCs. Windows 10 users have the possibility to install the update manually if they don’t want to wait for Windows Update, and there’s also an upgrade path for PCs that aren’t officially supported, though Microsoft isn’t recommending it.

Windows 11 is also shipping on new PCs from Microsoft and its OEM partners, but it’s not the end of the road for Windows 10 yet: Microsoft will keep supporting the OS will be supported until 2025, and Windows 10 version 21H2 will start rolling out to all users next month. If Windows 10 will remain on a bi-annual release cycle, Windows 11 will only receive new major updates once a year.
