Windows 7 is the last usable one. You probably meant 10 and/or 11.
Agreed. It was what I kept running under emulation for years when I still had to maintain backward compatibility with IE on some sites. It was the last one that was actually a user-first OS as opposed to a corporate-first ad platform.
Actually I forgot what it was like. I have not used it in decades.
But it's all malware nevertheless and with each new version you can expect it to become more aggressive (e.g.: Pluto).
You forgot about 8 (likely for the better.)
The thing wrong with SW is postured elitism over other software from clueless users like you who just like to spread FUD.
