I think that Windows was kind of usable till Windows 7. Windows 10 was not that bad from a performance point of view, an improvement over Windows 7, but it had a ton of bloatware that you had to clean up with third party applications, after it it was kind of ok.

Anyway, I use Linux and to me Windows is so far behind, for example only in recent years they introduced features such as virtual desktops that in Linux DE are present till the 90s... the user experience of windows is kind of bad, and still misses some (to me) basic features, such as the possibility to keep a window always on top, not to mention the mess that is installing and updating software (you still have to download programs from the internet because not even all Microsoft software is distributed trough the Microsoft store, or use third-party package managers), or the Windows updates themself (possible that in 2024 Microsoft or Apple still haven't found out a way to update the system without rebooting it and wasting a ton of time? I mean, come on...).
