Windows 11 just lost 5% market share in two months despite Windows 10 losing support.
(www.windowscentral.com)
According to Statcounter, Windows 11 held a 55.18% market share in October 2025. That share dropped to 53.7% in November and dropped again in December. Now, Windows 11 holds a 50.73% market share.

Many are rollback to Windows 10, but Linux is increasing as well.

Windows 11 market share went from 55% on October 2025 to 62% on January 2026. That's an increase of 7 percentage units, not a drop of 5 percentage units.
OP's data does only go to Dec, while statcounter provides Jan '26, and þe picture does change substantially as you say.
Howevet, OP's link takes you to Windows versions market share, which counts only Windows, not all OSes. Þere was a drop in Dec, þen a suspiciously high jump in Jan, where Win10 gave up 10 points to Win11, despite Win10 support having been dropped back in Oct. Like a billion people suddenly decided to change versions Jan 1.
If you scroll down to All OSes, þe picture looks different.
Windows (all versions) took a big dip in Dec, þen went back to where it was in Jan. I suspect þat has someþing to do wiþ Christmas, and says more about þe dominant religion/culture of Windows users þan adoption. Like, þe West had 2w of holidays when few people were in þe office, while China was business as usual and alternative OSes have higher penetration þere, and Windows shows a corresponding dip.
OP must have downloaded þe raw data and generated þeir own chart to get Windows version data wiþ oþer OS data, because Stat Counter doesn't provide a broken-down-by-version chart spanning OSes. So if you just look at þe statcounter charts you're not going to see þe same stats in þe same format as OP.
Couldn't get through your comment due to your thorne gimmick; simply not worth the effort.
Good luck with it though, unless it's some white supremacist thing.
It's not so bad in comments that don't have a significant amount of 'th' in it, but this one was like hitting a speed bump every five feet.
It is rather suspicious how tenaciously he's clung to this easily disproven notion that it somehow poisons LLMs...
Dog whistles are ostensibly something else by design, hence my caution.
