You can set it to go back to 2009. Apparently it hit 3% in Q3 2023. And apparently Windows has steadily been trending downward from 95% to 73% since 2009, which is wild to me. I find it hard to believe that that isn't due to other factors like increased smartphone use over desktops.
I understand that, but if people stop using desktops entirely (because they already have a phone in their pocket), the remaining users might be more likely to be on macOS or Linux for a specific reason.
I don't see the methodology on that page so it's hard to say for sure.
